I had a Pico 4 VR headset for a while, and there's this software called UEVR (I think that was the name) that lets you turn any Unreal Engine (I think 4 and 5)game into steresocopic 3D. It wasn't plug and play and you had to tinker quite a bit, but it was doable. I played most of Trepang2 this way and it was great. This was done by a single person IIRC, I believe Valve could do something even better if they get to it.
You could try CachyOS on the Deck, I used it for a few months and it worked great. It's practically the same as SteamOS but with pacman and paru available, with all the advantages this brings.
I sold my Deck and bought a Legion Go, and I'm also using CachyOS here. Same results.
Snatcher (1988). Cyberpunk text-heavy adventure by Hideo Kojima. The MSX version was fan-translated and the Mega CD/Sega CD version received an official English localization a few years after the PC88 and MSX versions came out.
And ripping off their customers.
