Thanks for that, I was trying to figure out what "Unity" was in this context, given that Ubuntu had something with the same name as it's main UI for about 7 years...
Like, what's the point of an "operating system UI" in a Linux desktop environment?
But then, I also don't get the point of doing that in some game engine called Unity.
I mean, is that a viable way to do a desktop?
Maybe it's just satire about flashy but useless eye candy.
When you're running lots of VMs, you end up using as little RAM as possible. It used to bug the hell out of me that Whonix came with KDE. Now finally they switched to XFCE. My Debian VMs get 1-2GB, and some script-laden sites can freeze them.
The linked one is particularly polished; it would have taken ages to implement all those little details.

There's several examples - Simulacra, Emily was Away, Hypnospace Outlaw - that use the interface of an (imaginary) computer as their primary framing device.
Or it could be useful in an immersive-sim type game where there happen to be computers you can interact with; you could immediately see the applications in some kind of hacking-themed game.
So yeah, I get it. Of course there'd be computers in games.
But once you have an OS in a game, why not just run a VM? Or would that use too many resources?
