It's even worse.
They are adding Linux support - but only if it detects you are running ~~the exact model of OLED screen as Steam Deck has~~ on SteamDeck, and blocks every other Linux device.
EDIT: There is some kind of hardware validation that can't be easily spoofed, I vaguely remember reading it was based on the screen HW, but that's beside the point.
Shadowrun kind of does the same. It's not really super-advanced, since it's cyberpunk, but it's cyberpunk with magic. And it's my favorite setting, it's such a cool idea.
