l'aventure de canmom à annecy - épisode deux: XR

so I'm going to abandon all semblance of chronological order at this point.

just like last year there was an VR room operating on a morning booking system - each thing had two headsets and a signup sheet. I didn't get to try every one but I did get most of them. enough that the volunteers noticed me coming back every day x3

^ some random people immersed in the Wired

this is easily the longest annecy post so far... so please read on for a big old discussion of the unique difficulties faced by VR film as a medium, and how this year's annecy films meet them... or more often don't.

so annecy's vr films section is for essentially linear vr projects (i refuse to write "experiences") that can be watched/played in less than an hour. i don't know if that's a hard rule but that's how long all the ones here were!

let's get the technical stuff out of the way: the Quest 2/3 was by far the headset of choice. some ran natively, some were PCVR with a wire connecting to a computer, and some were 360° videos which played back on the headset with 3dof tracking. some had a degree of interactivity, up to about a 'walking simulator' level. the average runtime was between 20m and an hour.

the preamble: on the limitations of VR

the big question I have with XR movies is basically... how well does it actually use the medium? like, is it doing anything that wouldn't work better as a flatscreen game or a film?

this might seem like a high bar to clear, like why shouldn't it be in VR - but VR is uncomfortable, the headset is expensive etc etc, and that's before even the formal stuff I'm about to get into. so that's 'why not'. and also, this is a new medium, I want to see what unique features it has to offer!

I'm sure I've said this before, but despite on the face of it being more 'inmersive' than traditional flatscreen games or films, VR is actually a pretty restrictive medium! compared to flatscreen games with their many 'buttons', you are very limited in the possible interactions. your main interaction is to 'pick up' and 'hold' objects, but this is close enough to actual physical interaction to highlight how much it isn't. what it actually means is that you position your hand or controller in a trigger and press a grab button or pinch your fingers, at which point the object snaps to your hand and moves weightlessly with it.

you also can't accelerate the pov too much without causing motion sickness, etc etc.

ok, what about film? well, compared to film, the big big thing VR lacks is the frame of the camera. you can't cut, you can't frame a subject, you don't have long shots or closeups, you can't even rely on the player/viewer looking in the direction of an interesting thing.

since movement is also tricky in VR due to the motion sickness problem, you're also limited in your ability to steer the viewer to interesting sights with Valve-style 'vistas' using the level architecture. it's not impossible - Valve themselves have their familiar vistas in HL Alyx - but it's something that depends on the player being able to move through a large space, so it doesn't fit these kinds of movie-like project so well. otherwise you can draw attention to a direction using various means, like visual effects that converge on a spot, or just keeping most of the action in the same area.

what you can also do, closer to camerawork, is move the viewer's point of view, and shrink or enlarge their surroundings. the language of VR 'shots' is still far from defined, but we have a few recurring ones: standing in a normal sized room, the giant's view in a tiny city, the floating perspective looking down on a diorama, the ant's eye view inside something regular sized.

how about theatre, which also has most of these limitations? well, compared to being in person with a real human being, you're limited by the capabilities of realtime animation systems and the rendering tech available on the device. you're looking at the character in a slightly fuzzy low resolution and unless you have AAA money which noone in VR does, you're a bit limited in the 'acting' you can pull off. this may change if the apple vision pro gets popular - apple already have a 'gertie the dinosaur' style demo where a very detailed dinosaur emerges from a portal - but it's definitely out of reach of most teams working on the Quest.

so compared to all these other media, what does XR offer?

compared to film and theatre, there is the game aspect of agency: a story feels different if you are the one doing it. so most VR narrative games have characters interact with the player somehow, though this introduces the problem of how to write the player into a story without feeling like you're railroading them or that they're superfluous to the real story.

it's very easy to undercut this sense of agency by having an amount that's not zero but still too small, e.g. if it just feels like the player is touching a button that lights up then you wonder why they even bothered.

the role that most games put the (vaguely defined) player character in is 'terrifying violence doer'. this is a fairly easy role to write around, and it gives the player a lot of control of the 'how' while letting the writer control the 'what' and 'where' and 'why'. similarly if the player's role is something like 'puzzle solver'. but for a purely narrative presentation, these roles don't exist.

still, this is the idea that a lot of VR rests on: an 'immersive experience' which puts the player into the story.

the other big thing that VR has is the joy of experiencing visual effects in 3D. particles, trails, transforming geometric shapes etc are cool on a flat screen and even cooler in stereo vision where you can move your head around. another benefit is spatial audio by default - something that is gradually coming to games but provided 'for free' by vr consoles.

in the land of games, you also have incredibly precise position and direction input... as long as it's in arm's length of the player. the most successful genres of VR games (so far) use this: a lot of shooting games, and some games that let you interact with physics objects, offer 3D jigsaw puzzles, or simulate sports to provide some real exercise. it can be really good for rhythm games as beat saber demonstrates.

VR is also really for social games like VRChat - similar to MMOs but with the benefits of more complex tracking in lieu of canned animations.

but... none of these fit the form of a predictable 15-50 minute narrative sequence! they're not films! so the VR films category at annecy is a tough problem to crack.

last year, the VR project that most impressed me was one that put you in the seat of a novice spotter in a bomber in the second world war. this was a great fit for a lot of reasons. you are in a vehicle so you have no reason to move from seated; the scenario is full of loud scary sounds that can make full use of spatial audio; your 'character' is well-defined but also doesn't have much reason to speak within the scenario. this had a small amount of interaction (by pointing your head) which you could actually fail, making it a bit closer to a game, and also giving you reason to play close attention to the bombed out cityscape below you. it did a fantastic job of capturing the tension of a dangerous air mission, the pilot character interacting with you was compelling, and overall it really benefited from being in VR.

this year's films

sadly nothing I saw this year comes close to that. but still, some are interesting, so let's go through them!

My favourite this year was probably Flow - completely unrelated to the movie in the main competition, though they share the trait of being completely wordless, conveying their story simply through imagery and music.

Flow's big trick is a very cool visual effect where characters and objects are conveyed the trails left behind by little particles, causing them to appear ghostlike . At first you're just flying through a cityscape, passing various people on the street and in the subway, with the particle trails conveying the breaths of the passengers; gradually a storm brews, the trails becoming the wind that tears at everything.

I believe this was a prerendered film, with only 3dof tracking - i think i saw some compression artefacts at some point. So it's less technically impressive than if they managed to do it realtime but it does make full use of the power this gives to render loads of particles and move rapidly through different scenes. it was also an effect that benefitted from the ability to put you in the middle of it - something that would not work as well on a flat screen.

But it also benefitted a lot from being more film-like. It has an original soundtrack, and progresses without input from the player. There's no awkward 'player' character to write around, no space you stand about in. The film can simply unfold and let you appreciate it. In this case, no interaction is better than bad interaction.

My Inner Ear Quartet from Japan did not do anything particularly novel with the medium, but to my mind it had by far the most compelling story. It tells of a young, introverted boy who habitually digs in the dirt for objects that other people would consider trash. The title refers to a string quartet which he hears when he cries, imagined to be in his inner ear; also there is a pair of tiny shrimp which he saw grow in a net.

The first half is narrated by a man who turns out to be the boy grown up, now a hearing aid salesman. While the boy abandons his box of treasures, as an adult he returns to collecting and documenting abandoned objects as a kind of urban explorer.

The geometry here is stylised in a kind of rough, children's drawing way. I think this could have been pushed further with more complex shaders but it works. For the most part, you're watching as an invisible observer seated on a floating chair. At certain points, the viewpoint is taken inside the boy's ear, or into the tin of treasures, where you can grab the objects and get the boy's brief, poetic description of each one.

I liked this story because it had substance, but left enough up to interpretation to be engaging. By showing the treasures to us with the descriptions we get to understand why they might be significant to the boy. It plays well with the classic anime theme of objects as vessels for emotional significance. I think it would have worked just as well on a flat screen, but I enjoyed my time with it.

Now the rest...

The Age of the Monster had some things going for it, but honestly I think this one shouldn't have been in VR. It's basically a film about how bad we're fucking up the planet, putting us in the house of a man who works in the nuclear industry in the 70s up to a future where the cooling towers lie in ruins. The 'monster' is a giant anthro catfish, seen first as a B-movie monster and dream vision and finally as a real kaiju scale creature in the final future scene.

We're told about the economic circumstances that led to the man getting this job, and his relief at working in nuclear during the oil crisis; we're told about the infamous repressed oil industry report about how climate change is gonna be a thing; we're told about the man's fraught relationship with his radical daughter who is furious about his extractivist ways. Then we get a collapse and humans learn to take the force of nature more seriously, i forget the exact phrasing they used.

The main problem is? These are mostly things you are told, by voiceover. There is some environmental storytelling in the evolution of the house but not enough to convey much without the v/o. the film does not seem to have the confidence in its imagery to show us what it's trying to say.

I feel like the film's vision of the post-collapse future, with flocks of birds flying over a wide river and collapsed overgrown cooling towers, is a huge missed opportunity. Here's an opportunity to apply some true visual imagination of how humans might live in a climate changed future... but nah, giant catfish kaiju just kinda hanging out there.

t

The environmental message is generally a stance I sympathise with, but the film doesn't make a good case for it on a propaganda level. We see the cooling towers outside the window and eventually the house, flooded, but it does little to make the collapse narrative emotionally compelling - and I question a little the choice to make it nuclear focused in a film about climate change. It's probably based on an actual guy, right? Maybe someone's parent? But... despite putting us in his shoes i don't really feel like i understand him very well.

Does this seem harsh? I know full well how involved vr dev is, and even simple things can take weeks. But i also want someone to make the most of this medium. To make something as compelling as the best short films on the main screens.

Gargoyle Doyle tells another 'skipping though time' story, depicting a gargoyle on an 800 year old church from its construction through to demolition. I would compare this one perhaps to a puppet theatre - it certainly stands out in terms of character animation, with Doyle played by Jason Isaacs as a classic grumpy old British theatre guy, his foyle foil a goofy statue of monk acting as a drainpipe with a penchant for puns.

I didn't get to watch this one in full, since I got to sub in for someone who left early (thanks to the volunteer who took pity on me when it was fully booked lol). So I didn't see the full arc of this. What I saw was... definitely edutainment material, but pretty well done. The player is cast as a visitor to a future museum and nature reserve built on the site of the church. It seems like this was originally shown in a real museum in Venice, with the 'in the museum' sections portrayed in mixed reality; obvs this wouldn't work at Annecy so they have these virtual too.

The narrative as a whole seems a tad self congratulatory and pat, with Doyle learning a valuable lesson about not being a cunt to his only friends as he's resurrected in the museum, and it doesn't do a whole lot with the VR framing, but taking it as an educational puppet show, it works pretty well - the voice performances are good and the jokes, while a little predictable, work for the kid-friendly style it's going for. I'm not sure it really needed to be 40 minutes long, but I can see they wanted to go maximalist for a proof of concept like this. It is kinda limited by the rendering capabilities of the Quest, the lack of shadows in particular, and could definitely benefit from some baked lighting given the relatively static scenes, but I give it a lot of credit for the character animation and VA.

Apparently the jury liked this one too because it won the competition!

Nana Lou has been in development a few years apparently, casting the player in the role of a psychopomp spirit whose role is to ease the passing of a woman dying of a stroke. Visually, this is one of the best looking, with elaborate forest scenes and strong environment design.

What I really like about this one is its use, at times, of a diorama-like presentation where the player looks down on tiny characters in a room. This is a concept I've wanted to try in VR for a while, and it's cool to see someone do it.

I found the kind of spiritual aspect of the story a lot more underwhelming. The player is accompanied by two other spirits who explain everything that's going on and point out the significance of all the imagery. The player is informed they have an important role, but they don't have a name and can't talk back, and the only interaction is to grab floating photos to initiate flashbacks.

I wish this film had had the confidence to trust in its acting and visual storytelling. While Nana Lou's life is a bit too lacking in serious conflict to make the premise work, it would still be far more interesting and compelling with the frame story largely trimmed. You could still cast the player as a psychopomp but you don't need to have a greek chorus telling them what to click on!

The actual story concerns Lou's relationship with her daughter, who became estranged when she quit university to raise her child, instead of staying on as Lou thought she should. This caused them to spend decades estranged. Finding out this story frees up the daughter's spirit as well, and the penultimate scene has her speak to Lou and make up.

There's definitely something to work with there, but the main delivery mechanism is rather ponderous narration triggered by interacting with objects, with the dramatic scenes largely having taken place off screen. Like The Age of the Monster, it suffers a severe telling-not-showing problem.

It's a shame because there are nice touches here. When you are beside Lou's bed in the hospital, your touch leaves a glow effect which is very evocative. The acting is solid, though the script undermines it a bit.

I don't think narration is evil - evidently, Yuri and I used it in our film, it's a very efficient way to convey information - but I do think it requires a lot of thought put into style and rhythm.

Spots of Light... ok. This one tells the story of an Israeli soldier who lost his sight in the Lebanon war, and later regained it temporarily through surgery. Given my general feelings about the Israeli military (presently carrying out a genocide), I was definitely not disposed to like this one. Nevertheless, it was the only one free so I decided to give it a shot.

This is one of those films where you interview someone and then put an animation to it. So this guy tells you what it was like to be blind and then not blind to see his family briefly, and it's illustrated with various images. And (if i remember right) some parts are on tvs showing video (and if you're using vr to embed a flat screen what is even the point??). When he's blind, everything disappears except vague outlines suggested by small points of light.

Ultimately this is a film about blindness, not the war (of course, meaning this is a person who could leave the war behind - though not to make light of the cruelty of conscription). Making a film about the experience of blindness in a purely visual medium is a choice all right, and I don't feel like this film expressed anything unexpected about it - he was sad to lose his sight, glad to see his family, depressed to lose it again but ultimately at peace. Which is conveyed, of course, primarily by narration.

So yeah this one didn't do much for me!

Stay Alive My Son, now. Agh. This one was... this one was a mess.

So this one is about the Cambodian genocide, right. It's based on a memoir by a survivor of the genocide, Pin Yathay, who became separated from his wife and son while fleeing the Khmer Rouge.

The way this is presented is essentially a walking simulator that takes you through a dungeon-like environment full of skeletons. Every so often you encounter 3D films - filmed with some kind of depth camera - showing actors playing out scenes from the life of the family. There is also a frame story where you visit Pin Yathay in his modern day house, where he sees a digital reconstruction of how his son might look as an adult

This one is difficult to review because it was severely marred by technical issues with the spatial audio, which caused the sound to cut out when you turned your head the wrong way or moved it to the wrong place. It would probably be less of a rough experience if the audio worked as intended. Nevertheless, I have plenty of reservations with the way the story is told as well.

It seems the director of the VR experience (fine! I'll write experience, there isn't a better noun for this kind of thing that sits between game and film) met Pin Yathay, there's video of her speaking to him at the end, but he had pretty minimal creative input beyond providing inspiration through his memoir. So this is a Greek/US interpretation of the Cambodian genocide. The narrative it tells is basically: Yathay and his family are living a pretty idyllic life, then the Khmer Rouge happens, seemingly not for any particular reason. Yathay and his family are evacuated and then put to hard labour growing rice; eventually, their son is put to work too, so fearing for his life, they flee into the jungle.

The Cambodian genocide is - obviously! - one of the worst atrocities of the whole bloody 20th century, and the circumstances surrounding it are worth reading about (though pretty unremittingly bleak). But you won't learn much about, say, cold war geopolitical alignment, Prince Sihanouk, the absolutely horrific civil war, the different ideologies in play in the Marxist milieu that influenced Pol Pot, or the spillover from Vietnam and the massive bombing by the Americans here which helped put the Khmer Rouge in power. You definitely won't learn much about the Cambodia that existed before the war. Instead, you're mostly traversing a dungeon that could come from any horror game, shining your torch on the things you're told to in order to unlock another segment of narration from (the actor playing) Yathay. It is, in pretty literal terms, a tour of atrocities.

Unfortunately the '3D film of actors' conceit doesn't really work because... even audio issues aside, the acting is pretty unconvincing. For some reason - perhaps that subtitles are tricky in VR - the dialogue is in accented English rather than Cambodian, and it's pretty quickly evident that they just have one guy in the role of 'Khmer Rouge soldier' and the lines he's given are kinda awkward. The horror game aesthetics of the environments and the amateur actors and costumes all clash pretty badly. The 3D filming is also kind of jank, only really working if you're fairly close to the camera position, so you aren't really free to move too far even if the audio didn't crap out.

The basic feelings it's trying to explore - the horror of living through a genocide, separation from a child, guilt for abandoning him, not knowing if he's alive or dead - is definitely worth depicting, but honestly this would have been far far better expressed as a 10-20 minute film than a slow 55 minute VR walking sim. The more abstract bits toward the end with paper plane imagery and a Buddhist temple (where you have to put a block in a slot to unlock a door) also feel too jank and videogamey to really have much impact, though by that point I had been wrestling with the audio for nearly an hour so I wasn't in the most receptive mood.

But all the execution flaws aside, that leaves the question of what even is the right way to portray a genocide artistically? This approach is very abstract, reducing the events to dislocated symbols - propaganda posters, the tree against which children were dashed - which perhaps might reflect how fragmented memory becomes, but seems to be wasting the potential of VR to establish you in a place. But then, I guess rice fields are harder to render than enclosed dark rooms.

Speaking of rendering, this was PCVR, so your torch casts shadows and it has other features that would be hard on realtime. But the lack of ambient light and general harshness of the materials adds to the 'horror game' feel.

There is something here about how genocides become associated with certain images. For Cambodia, it is primarily phrases like 'killing fields' and the stacked skulls in the genocide memorials such as Choeung Ek - few people know the name of the memorial in the west, but I think everyone who's heard of the genocide has seen the big stack of skulls. I imagine this is what all the skeletons in this experience are supposed to call to mind: they're representatives of the many ways people died. The problem that this kind of environmental storytelling has long ago been made kind of camp by videogames. A photo of a stack of real skeletons still has power to disturb, but less so a low poly 3D skeleton.

Should it have tried for a realism? The idea of trying to realistically simulate the experience of living in Cambodia though the genocide is kind of ghoulish, and I'm glad they didn't take that approach. But the 'tour of images' approach falls flat. I think The Most Precious of Cargoes elsewhere in the festival makes a stronger case for how to approach a topic like a genocide in a consciously constructed way, but it also has the ability to be in dialogue with a lot of other films made about the Holocaust. There is less in English about the Cambodian genocide - the viewer can't even be assumed to know what happened.

Overall, I think it would be possible to make a much stronger film about the genocide in Cambodia. But I'm not sure what that film would look like. I did learn one thing from this story, which is that there is a reality show in Cambodia which shows survivors of the genocide being reunited with their families. Not much is made of this here, it's something of a background detail. What would it be like to grow up in the shadow of an event like that? I wish the film had been willing to portray more of modern Cambodia - and I hope at some point someone in Cambodia will have a film at this festival, in VR or not, which can talk about it all from the first person.

Is there a good way to try to answer the curiosity of people who live safely in rich countries about what it is like to go through an actual genocide... using a Meta Quest 2 VR headset that costs a few hundred quid? I don't really know, but this film could have done with being a bit more reflective, I feel. So it goes.

the others

there were three films I couldn't see - The Imaginary Friend, Oto's Planet and Emperor. If I get some other chance to try them I'll write about them too!

Overall I felt a bit disappointed with the VR this year, but also I kind of want to put my money where my mouth is and try my hand at making this kind of thing. I do have the technical knowledge at least!

If you read all this, thank you.

Prompt #1: Steer

“Adra! ADRA!”

Thud. Thud. THUD. THUD.

“ADRAAA!”

Blaring alarums almost drowned out the sound of Sven’s desperate efforts to break down the door to the engine room. They overlapped in a deafening, discordant rhythm as multiple systems reported critical failure throughout the ship.

Shut up, she snapped at him in her mind. Winding her fingers through her hair, she grasped handfuls of it as she paced the narrow corridor. Shut up, I need to think.

Above her, a valve blew its gauge. There was a metallic pling as a bolt shot across the room. Steam started to hiss, misting the air with oppressive, humid heat that made every breath feel like a gulp of warm water.

A saboteur had infiltrated the ship and meddled with its mechanisms. She surmised that much when she realised she was locked out of her failsafes. She was going to die, but that was fine. They didn’t all have to. Sven wouldn’t. Not if she had anything to say about it.

Arterial pipes ran throughout the ship. First, she had to close them. That would localise the damage to the room she was in—its insulated belly, the beating heart of the vessel, currently in the throes of cardiac arrest. The ship had more hope of staying in one piece if she could. It would still go down, and every system aboard would lose power, but they could control the descent.

As she set to work, readings poured in and streamed down a flickering console to her left, distorted by visual noise and the crack across the screen.

AUXILIARY TEMPERATURES ABOVE SAFE THRESHOLDS

You don’t say. Drenched in sweat, she could feel the very walls around her radiating heat. Each time she touched the console had to be brief or her fingertips would blister.

SAFEGUARD PROGRAMME ‘DELTA’ : FAILURE TO DEPLOY

We’ve exhausted plan B, then. Not that she’d held out much hope that any of her contingencies would save them at this juncture.

CORE PRESSURE LEVELS: CRITICAL

I know it hurts, old girl. Hold on just a little more, for me. All she needed was a few more precious moments. Adra knew she didn’t have them.

AETHERIC MODULATORS NOT DETECTED

That was the one that troubled her the most, because it suggested they’d been fried. But where was all that aether coming from?

A massive concentration of condensed, aspected aether would cause an explosion. It was going to happen. All she could do was decide where, and when. She’d have to manually direct the channels utilising analogue controls and trigger the detonation, because if this had to happen, it was happening by her own hand.

She’d been in two minds about installing aether-based technologies. It wasn’t easy finding engineers with the requisite expertise, and she didn’t like dealing with aether. Its raw form wouldn’t heed her, nor could she operate the technology required to direct it. She couldn’t abide the idea of entrusting that much power over her own vessel to someone else.

But the potential had been too alluring to deny. They’d tried to adapt a teleporter relying on the same principles utilised by aetherytes. In theory, it could warp the entire vessel and all its crew to another location instantaneously. In theory, because she’d never gotten it working. And now that useless chunk of crystal was going to destroy everything she’d achieved, everything she loved.

But not everyone.

Pipes burst around her. Searing hot ceruleum streamed down the walls, melting the metal in its path. A small explosion rocked the ship, and Adra was forced to hang onto a burning hot valve to avoid being tossed to the ground. It was now, or, well, now.

Grasping the lever with both hands, she pulled back. Every measure in place to prevent catastrophic failure was simultaneously deactivated. The result was instant. She didn’t have time to scream, feel pain, or regret the fleeting fragility of life. A soundless white flash engulfed her.

And then she woke, soaked in sweat, in her cot in the engine room. Its rhythmic purring assured her all was well. This was the CETEA, and she was en route to Kugane.

This dream, again.

When she’d heard what had happened to an unlucky number of the Unsung and one member of the crew, she’d been reminded of what had happened all those years ago. The similarities were plain. She’d even found herself flinching when she felt the explosion in the hangar as it shuddered through the ship.

An infiltrator. An aetheryte. A sudden displacement… even the destination was—not the same, but near enough to Doma. The only difference was that it hadn’t been her, this time.

She was still here.

It was time to get up and back to work.

[wirewitchviolet]

I hate Steam, and it's weird that you don't.

Easily, hands down, the single worst piece of software I have ever had on any computer is Steam, the game shopping/library/I-guess-social-media-app? from Valve that I'm fairly certain anyone who has ever used a personal computer to play a video game within the past, what, 20 years or so, is quite familiar with. It's ubiquitous. People have a level of affection for it they get kinda frighteningly weird about. But it is honestly JUST THE WORST, and I'm going to ramble about why for a good bit under the fold here.

I hate Steam as a store.

Primarily, Steam is a storefront. If I want to purchase a game to play on my computer I can, and often have to, either launch this here app or use the same credentials on a website, where I can fill in my credit card info and, one would assume, get a copy a game I can then install and play. But uh... while this is nowhere near the top of my personal list of issues with Steam, it is worth noting that that is not actually the nature of such a transaction, really.

What I am really paying for, in practice, is for whatever game it is to be "activated in my Steam library." That means I can then open the Steam app, pick that game off a list, and click a download button, which WILL grab all of that game's files from a server and copy them onto my computer, but not in the form of an executable application I can move around and properly back up and launch on its own. Rather, what I have downloaded is a plug-in for the Steam app that will let me launch that game from within the Steam app, if the Steam app is currently connected to the internet and having a good day. In every other context where any other piece of software pulls that kind of crap, everyone quite rightfully throws a fit over it, and frequently will outright refuse. Sometimes things go to court over companies insisting on this weird level of control and spying over the files people have on their own computers. I have plenty to get into about this later, but I'm still not done griping about Steam as a store.

Because see, sometimes, exchanging money for a game to be activated in a steam library doesn't even work. For whatever reason that I'm sure makes sense to someone's accountant, activation of a game in a steam library is based on the use of I want to say 16 character unique "activation keys," and sometimes they run out. Admittedly this issue comes up more frequently when I am acquiring a game from somewhere other than steam- a giveaway the developer is running, buying something from the Humble store and getting a steam key from them instead of a direct download, backing something on kickstarter, whatever. But PRETTY FREQUENTLY, I give someone my money, and in return I get a little notification that "Steam keys for this product are not in stock." I don't get my money back. I don't get some kind of gift card to use on something else. I just get, "welp, sorry! We don't actually have the thing you paid for available! Check back sometime later and we might?" And the operative word there is might. There are games I've paid for whose keys have been out of stock for YEARS. Oh and sometimes, those keys expire! I pay money for a game, get what is essentially a tag to take up to the front counter, and if I don't get on that, someone just pockets my money and I get nothing. Sometimes this happens THE DAY I PURCHASE IT. Sometimes THE DAY BEFORE I PURCHASE IT. No warning up front.

So, OK. Surely though there is some upside to this weird key tracking setup, right? Like if I somehow get into a situation where I have a key for a game that I already own (perhaps it's my birthday, and two people both decided to gift me the same game that I had on my wishlist). I have the one activated copy. I put in this second code and... here's a message that I already have this. Oh well OK. Will you refund me for the key then? No. ... can I pass the key along to someone else who also wants that game? I believe it depends, but the answer is at least sometimes no. Especially if there's some sort of sale or bundle involved, no splitting those keys up between several people, arbitrarily. Steam is all too happy to just take your money in these sorts of situations and give you nothing in return. Hell, I can think of at least 3 or 4 instances when I have ended up with an activation key or an on-site sales button for a game with various DLC expansions included, and because I already owned the base game, I was unable to activate this extra copy with the DLC included. No DLC for me, no refund.

Those pretty serious issues aside, it's just... really badly laid out and run as a store. Plenty of people will gripe about how hard it is to find something, or how there will just be a weird mix of porn and shovelware (often describing the same game) on the front page, but even just working out what you're buying or what a sale covers is kind of a confusing mess? Like right now, going to the front page, here's a big Wales Interactive sale. Let's just click through that and... OK what the hell is this complete mess? Don't judge me if you see "in library" on garbage by the way, it was all blind box bundle stuff. Anyway right at the top of this special dedicated sale page we've got

OK the one horror thing is 25% off... or 27% off with its DLC. The other is 81% off. Let me just scroll down more though...

OK so wait the one game they're really pushing the hardest here has a deluxe edition, an ultimate edition, and a collector's edition. All on sale, I think all with the DLC bundled in... and like, this version here is "-20% -33% so $51.66" and this other version which comes bundled with a whole other game is "-10% -58% $21.14" What are we even trying to convey? In what world would the former be a good deal? And those FMV bundles are similarly confusing. Well, let me just click through and see if it's clearer looking at just this one game and see if that clears it up?

No! Somehow this is even more confusing! I can however apparently buy just this game, if I were inclined, for MORE MONEY than buying this game bundled with this other game I already own. Why? How? Or if I want the DLC, I can get it with all the DLC for $50, OR I can get it with all the DLC for $30? Again, I am just incredibly confused, and glad I really don't have any desire to own this and don't need to care.

I will say though that the first time I ever purchased anything from Steam it was when they were running a sale like this on the Oddworld games. The confusing as hell bundle buttons and redirects and such set up a world wherein I had the option of getting literally every Oddworld game to date (this was before New and Tasty was a thing) for $25 OR I could get a bundle of every game except for Munch's Oddysee... the one game I had never had a chance to play before... plus those were uh... older buggier PC ports apparently. Anyway something bugged out in the cart, I had two identical things in there, just listed as "Oddworld..." and I end up charged for the.... objectively terrible option instead of literally that plus a whole other game.

So you know, IMMEDIATELY, when I see the full list of what I'm actually getting for the first time after hitting confirm, I see something went wrong, and promptly set about trying to cancel that/order the correct thing/get hold of some tech support person because hey what the hell? Now with LITERALLY ANY OTHER STORE, this would get taken care of immediately. Online, brick and mortar, whatever. In person? "Hey, I gave you the money for these 5 things, you only put 4 of them in my bag." "Oh sorry, here you go!" or "Hey the wrong thing was on the shelf" or "hey this literally wasn't in the box" these get sorted. I've had online stores literally send me completely the wrong order, got that sorted out. I've ordered clothes that didn't fit, they refunded me and didn't even want me sending the baby-sized one back. I once had a weird collision where a friend bought me a whole huge pricy bundle of games and software from itch.io, because she had contributed to it and wanted to share, meanwhile I bought it myself for the same reason. One quick support e-mail and I got them to send HER a refund, like within 5 minutes. Steam though? It has literally been a decade now, multiple support tickets, I still don't have my collection, no refund, nothing.

And you know just sticking with this a moment... appeasing customers upset about this sort of thing is kinda the one thing stores are for. If something is on sale in a store for $50, that store paid somewhere between $5 and $25 for that to whoever supplied it to them. When I buy it, I am forwarding along that small percentage of the price to the people who actually made the thing, and the rest of the money I am forking over is me paying the store for the service of making this a low stress low headache situation. Functionally that means I am buying insurance against random weird issues like... paying for something and not getting it. It happens rarely enough that the store still profits, but sometimes yeah you just give an angry customer whatever the hell they're haranguing you about, even if you're confused about what their deal is, so they don't spend the next decade griping to everyone about how terrible your store is to anyone who will listen and swear off ever shopping there again. Especially if they have a paper trail on how you didn't give them what they were attempting to buy. But anyway, moving on to the next problem.

Wait no! One more thing! It is SHOCKINGLY DIFFICULT to do gift shopping on steam! If I set up a wishlist, nobody can see it unless they're friends with me, and even then it's kinda weirdly buried in submenus to a point where I always need to search up a guide on how to even find it. And you'd think there'd be some option to just like... buy one of these keys everything is using for a game, and mail it to someone as a surprise gift, but nope. Not an option. Everything about buying a game for a friend or relative is like pulling teeth. In the store for buying games.

I hate Steam as a launcher app.

There is really no reason for launcher apps to exist. We are all perfectly capable of, say, putting all of our games into a nice little "Games" directory on our computer and setting a nice shortcut to that or whatever other little organizational things we might want to do. I will grant that just freaking displaying a directory is something Windows in particular is weirdly bad at, but it does a better job than Steam does. Just opening this window with a list of games requires a weird amount of startup, possibly a login, it puts a shocking load on processor and ram. It opens a big annoying pop-up ad. It signs me into a messenger app I'm never going to use. And when I'm done with it, attempting to close it out like any other piece of software on my computer just straight up does not work. In theory if I formally "Exit Steam" from a drop-down it will cleanly quit, but sometimes I forget, and I swear, sometimes that doesn't do the trick, and while it certainly looks like Steam isn't open from a glance at my taskbar, if I open up my task manager, here's like... 5 separate running instances of something called "Steam Web Helper" and one of them is eating AN ENTIRE FREAKING GIG of RAM! It is absolutely absurd for anything to ever be doing that. The only other thing I have that eats RAM that absurdly is my web browser, where I have like 200 tabs open across 20 windows at any given time, all loaded up with gross bloated sphagetti scripts instead of functional code. But it's not like this Steam web helper is secretly a web-browser opening pages up for every game in my library or anything right?

... no apparently that's what it is. Yeah all those screenshots, trailers, reviews, "community content" sections full of creepy fan art and Russian youtube LPs of games that load up in a full page splash zone when you're just trying to click the name of a game off a simple text list and hit launch are secretly a big web page we're quietly launching an invisible web browser to load up. And hey, even if you don't have that window open, it's still loaded. And even if you go mess with preferences and ask not to be spammed with all this stuff, it's still loaded. And even if you try to keep steam closed at all times to avoid the whole mess, it really likes to worm its way in to load on boot up and also update itself whenever it feels like it.

And hey! Speaking of updates! The real reason the steam launcher even exists of course is to serve as super aggressive DRM (the sort where even if you have single player games locally "installed," you can't play them if you are offline or otherwise unable to connect to Steams servers, and to spam you with those pop-up ads, but the sales pitch to keep you from just treating the whole thing as gross malware is that there is some convenience here. Doesn't matter if you have 10 computers scattered about, Steam will keep your favorite games all ready to go and fully up to date and cloud sync saved data between them so they can be loaded up at the touch of a button!

Well that end of things straight up sucks. I am inherently distrustful of automated updates in general. I tend to hit a version of a given piece of software I like, and from there on any further updates can only make it worse. Also, I like to have total control of when my bandwidth is being hogged. I don't want to be streaming a movie, or hosting a stream on twitch, and have oh... Steam, let's say, decide that 100% of my bandwidth is needed RIGHT THIS MINUTE, because there was a 30 gig update for I dunno, Granny Simulator. But... Steam feels differently, and will absolutely queue that up. Even after I dug through preferences looking for a way to disable that. Even when I don't have the game in question installed, and haven't had it installed for years, if ever. Aside from the serious bandwidth issue, I constantly find myself mysteriously out of disk space because Steam decided it was time to download a huge patch for some game or other I've never even touched, and I just have to go through like I'm hunting for mushrooms in a basement or something finding these unwanted games.

And it doesn't even really keep them up to date! I end up with games that are "fully installed and ready to launch" but when I try, I have to sit there for upwards of multiple hours after hitting launch buttons because oh, the installation process forgot that every game for some baffling reason needs its own personal copy of DirectX and 20 other software dependencies, and it just didn't feel like running the installers for those when installing the game.

The worst part though is the damn cloud sync saves. I have absolutely lost count of how many dozens or hundreds of times I have completely lost all save data for a game because some cloud sync failed, or an automatic update corrupted save files. Or less damaging but still quite annoying, I've lost my connection to steam while playing a game, causing my local save to be more up to date than the version stored on a server, and Steam's answer to that is TOO FREAKIN' BAD! There is, to my knowledge, absolutely no way to push a save file to the cloud by hand. It is always considered the master copy, and if it's out of date or corrupted, oh well. I didn't ask for this, I'm always playing on my one desktop, but I just gotta deal.

I... greatly dislike Steam as a compatibility layer.

So the thing with Steam and the separate copy of DirectX for every individual game is that IN THEORY, Steam does a lot of handy things behind the scenes to get older games to work smoothly on modern hardware. And it... often does a kind of OK job at that? I put it through its paces on that front more than most people do, streaming my whole library, which includes some 20 or 30 year old games, but... most of those are from modern promotions explicitly linked to Steam so you'd think those would all be guaranteed to... run, at all. Hopefully not too many would have terrible interactions with the resolution on my monitor. DOS games in particular tend to really suck through Steam. There's a one size fits all DOSBox solution, but... it's an old buggy version of DOSBox, and if I could just manually launch a more current and nicely customized one and run these things through that, and not have it, you know, completely break should I alt-tab away, that'd be nice. But I can't. Because aggressive DRM.

I hate Steam as a social media... thing.

Back at the dawn of time, I like a lot of other people made the mistake of picking AOL as an internet service provider. Everything about this was absolutely miserable, except for the whole Instant Messenger thing. That was a nice way to stay in touch with people that I used for many many years... and the reason I used it for many many years was that it was available as a small lightweight independent program I could still use for decades past when I swore off AOL forever. Steam has a little chat thing, but... it does not have that very important feature. I can't access my steam friends chat deal unless I am actively running this awful piece of software that eats more than half my RAM and fills my hard drive with garbage. And also, you know, I have multiple other ways to keep in touch with people. If I did use it though, I'd hate the UI. And I hate how you have to cut through it half the time to invite a friend to play a multiplayer game.

Beyond that, Steam has all this "community" stuff where... again, unless I actively disable it, I'm bombarded with weird LPs and fan art and this whole baffling ecosystem of neo-nazis spamming negative reviews at everything not staring a white guy and... reviewing each other's reviews like some kind of weird reddit gold system? Totally burying any useful information, and also throwing "user tags" on games destroying any sort of usable organizational info. And then there's trading cards? I've never understood what those are about. It all just seems terrible, and I want to be rid of it, and it definitely enables all kinds of horrible stalking, too.

I hate Steam as... you know, a general vestige of horrible capitalistic crap?

While Steam isn't the ONLY game in town as far as a store you can buy games from, it has enough of a stranglehold on things, and this weird cult-like following of people who I guess missed out on the whole 16-bit console wars thing and are hellbent on recreating it with... what stores people shop at. So there's a lot of baseline stupidity and aggressive weirdos from that, but also, as a developer, you really can't afford not to put stuff in the Steam store, which as I understand it is the absolute worst deal financially for any possible place you can sell a game these days, and forces developers to eat the loss with the constant weirdly advertised sales. Plus, you know, I personally have like... two or three thousand games right now which I can ONLY run if I have Steam going. Eventually it's going down and taking all those with them. Any unilateral policy changes Steam makes, we're all stuck with. Games get pulled without warning or recourse. Hell, game developers get snatched up by Valve on the promise of getting their stuff published and getting relocated to... maintenance projects on Steam with their projects killed. So that all sucks.

But again, mostly I hate the bloated malware aspect and them stiffing me on a game a decade ago. And it's weird that everyone seems to just give them infinite free passes on all this stuff while harping on anyone else they see doing similar stuff.

Engine specs for the 1st Gen Mitsubishi Pajero Mini.

Pajero Mini Detailed explanation

ENGINE 20VDOHC TURBO & SOHC 16VALVES

Two types of optimal tunes to suit your RV concept

Two types of 4-cylinder engines are available as the featured power units.

The VR series is equipped with a DOHC intercooler turbo that will satisfy sports enthusiasts and cross country users. The specs are top-class, with a maximum output of 64ps/7000rpm and a maximum torque of 9.9kg-m/3000rpm!

DOHC has 5 valves per cylinder.

Uno is common. However, this unit uses 3 intake/exhaust valves and an additional 5 valves, making it 4 cylinders with a total of 20 valves, and has a mechanism that rivals even racing engines. It goes without saying that the compact combustion chamber and excellent intake and exhaust efficiency improve power performance and fuel efficiency. On the other hand, having multiple valves has the disadvantage of increasing power friction, but we have taken measures to counter this by adopting an end-pivot type roller rocker arm to drive the valves and reducing the weight of the valves themselves. .

The turbocharger is the world's smallest twin-scroll type. Converting a light engine to a four-cylinder engine is useful for making it quieter and reducing vibration, but exhaust interference becomes a problem when matching it with a turbocharger. To prevent this, the exhaust gas is divided into two parts from the exhaust manifold and drawn directly into the turbo's scroll chamber. Low-speed boost pressure is significantly improved compared to single exhaust.

Of course, when installed in the Pajero Mini, special and detailed tuning has been performed. Intake and exhaust timing has been optimized to improve torque characteristics in the low rotation range despite the increased body weight.

In addition, to enhance the driving sensation without discomfort, To achieve this, a slow limited idle speed control and a non-linear throttle lever have been adopted. In situations where running resistance is extremely high, such as on sandy terrain, the power may suddenly be applied when starting, etc.

The initial response of the accelerator is made slightly duller to prevent sudden increases.

The other unit is a single overhead-cam, 16-valve naturally aspirated (NA) engine. 52ps/7000rpm、6.0kg-m/5000

The rpm performance and the mileage characteristics unique to NA are perfect for utility vehicles mainly used around town and for female users.

Not to be overlooked are the adoption of a large 4-liter chamber type in the intake duct and improvements to the inlet manifold that increase intake and exhaust efficiency at low and high speeds. The shape of the oil pan takes into account driving on slopes, and the positioning of the air cleaner relative to submerged waterways is a common feature of both units.

Transmission options include 5-speed and 3-speed AT. Improved mission based on minicab

It has a new case and is highly reliable. The first thing to pay attention to when using MT is the straw.

Short and reliable shift feel. This is a major advantage of a longitudinally mounted engine, but the careful design of the shift system, along with the direct shift control without wires, cannot be overlooked. Additionally, the VR turbo's system uses large-capacity double cone synchronizers in 1st and 2nd gears. Friction dampers are also used in 2nd and 3rd gear and reverse, making shift operations and quietness reliable and comfortable. Another characteristic unique to turbos is that they have a particularly low gearing compared to NA.

AT is an electronically controlled type that promises comfortable and reliable automatic gear shifting. A cable-type control system is used to prevent lever vibration and gear slippage when driving on rough roads.

Gate Valve supplier in Oman

Middleeast valve is one of the best  Gate valve supplier in Oman . We supply to cities like Ibri, Sur, Muscat, and Mutrah.

A gate valve is a type of valve used to control the flow of fluids (liquids or gases) by using a gate or wedge-like disc that moves perpendicular to the flow path to either block or allow the passage of the fluid.

The main function of a gate valve is to provide a tight shutoff, effectively stopping the flow of fluid through the pipeline when the valve is fully closed, and allowing unrestricted flow when the valve is fully open. Gate valves are commonly used in applications where the fluid flow needs to be completely shut off, such as in water supply systems, oil and gas pipelines, industrial processes, and more.

Gate valves consist of several main components, including the body, gate (wedge), stem, actuator, and seats. Here's how they work:

Open Position:

In the open position, the gate (wedge) is fully retracted into the valve body, allowing the fluid to flow through the valve with minimal obstruction. The gate moves perpendicular to the direction of the fluid flow. The valve is opened by turning the valve stem (either manually using a handwheel or with an actuator) which is connected to the gate.

Closing Position:

To close the valve, the stem is turned in the opposite direction, causing the gate to move down into the flow path of the fluid. As the gate descends, it gradually restricts the flow until the valve is completely closed. The gate makes contact with the valve seats located at the bottom of the valve body, forming a tight seal that prevents any further flow.

Middleeast valve is the greatest Gate valve supplier in Oman and are known for their ability to provide a tight seal and low pressure drop when fully open. However, they might require more turns to fully open or close compared to other valve types like ball valves. It's important to use gate valves in appropriate applications and avoid using them for flow regulation where frequent adjustments are necessary.

Globe Valve Manufacturers in India

Speciality Valve is a renowned and trusted Globe Valve Manufacturers in India, known for its high-quality products and reliable performance.

Think of a globe valve as a faucet to turn on and control the water flowing in a pipe. Its body is in the form of a disk, as well as in the middle of that disk is the inner disk shaped part called the pin. This plug is raised or lowered to adjust the amount of water going through the valve. When the plug is down, it interrupts the flow of water, and when it’s up, it opens space for water to go through. A plug can be turned by hand or it can be turned using a machine. When it comes to applications, globe valves are used in a variety of industries to control the flow of water, gas, or oil.

What is a Globe Valve Used For? Various industrial and commercial applications require globe valves to control theflow of liquids and gases. They are very much appreciated for their universality and stable work.

Features of Globe Valves

Globe Valve: A globe valve which has a spherical body with a movable disk type element and a stationary baffle. This baffle, or disc/plug, is attached to a stem that runs through the top of the valve. A handwheel or actuator controls the stem to raise or lower a disc to accurately be the positioning flow of the fluid through the valve.

Speciality Valve is the Largest Globe Valve Manufacturers in India & It offers a wide range of globe valve designs, including pressure seal, bellow seal, Ytype, angle type, and forged steel globe valves, catering to various operational needs.

What are the Advantages of Globe Valves?

Excellent sealing performance

Strong throttling capability

Shorter stroke than gate valves

Available in tee, wye, and angle designs, each with unique functionalities

Easy to machine or resurface valve seats

Can act as a stopcheck valve when the disc is not fixed to the stem

What is the difference between Globe Valve vs. Gate Valve?

Both globe and gate valves are used in industrial systems, each with distinct features:

Globe Valves:

Part of the linear motion valve group, suitable for oil and gas applications

Used to starting, stopping, and regulating flow

Have a spherical body and disc for tighter sealing and minimal leakage

Preferred for safetysensitive applications due to leak prevention capabilities

Excellent at throttling and flow regulation, ideal for highpressure, hightemperature, viscous, and corrosive systems

Gate Valves:

Feature a parallel or wedgeshaped disc with either rising or nonrising stems

Open by lifting the gate, allowing unobstructed flow and minimal pressure drop

Best for on/off flow control with minimal resistance, especially in fully open position

Can be installed in any flow direction, making them versatile

Structural Differences:

Globe Valves: Have internal parts within the valve body, designed for throttling and tight shutoff, leading to higher pressure drops.

Gate Valves: Simpler structure with internal parts at the top, creating a hollow body that minimizes pressure drops when open.

Functions of Globe Valves:

Control the start/stop of flow

Regulate flow precisely

Prevent leaks

Ideal for managing viscous, corrosive, highpressure, and hightemperature fluids

Functions of Gate Valves:

Provide on/off flow control

Allow minimal resistance to flow when fully open

Support bidirectional flow

Used for isolating sections of pipelines in industrial applications

What is the difference between Globe Valve & Ball Valve?

When comparing globe valves with ball valves, the primary difference is their operation:

Ball Valves: Use a rotating ball for on/off control, which offers quick opening and closing with minimal pressure drop. However, they are not suitable for fine flow control.

Globe Valves: Use a linear stem and plug for flow regulation, making them ideal for throttling but slower to open and close compared to ball valves.

Ball Valve Functionality:
