It’s possible they want to support Steam Deck without supporting the rest of linux desktop, which would just be… dumb. The Steam Deck, in Valve’s own words, is “just a PC” anyway.

Considering they unbanned all most of the linux users last time though, this is likely just another mistake.

Just be aware that “stable” in the linux world means “old.” All of the software in the Debian repos will be much more out of date than some other distros like Pop!_OS, Fedora, or even Ubuntu. If you upgrade to newer hardware, or want to use newer software, Debian may not support it without jumping through some major hoops.

DUSK and CULTIC come to mind. The original 1993 DOOM and 1996 Quake are also absolutely still worth playing, but it sounds like you may have already played them. Maybe Post Void, Cruelty Squad, or HROT if those seem up your alley.

I’ve heard great stuff about ULTRAKILL, but I would wait for it to leave early access before getting it.
