A gaming community free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it's price, waiting for bugs/issues to be patched, DLC to be released, don't meet the system requirements, or just haven't had the time to keep up with the latest releases.

Playstations that are old enough to become cheap to get but new enough that the local libraries still have a game collection.
Otherwise a Linux pc and gog, flea markets, local used sellers, or other sources.

Still mainly my PC/steam deck but I mix in the switch in there for specific games and the xbox every once in a while for spider heck.
Perhaps similar to OP, I gravitate toward whatever's handiest. That's usually my smartphone or one of a number of old-ish Linux laptops. I have a handful of smartphone games that I play pretty much every day, and I've got controllers for both, so there's also lots of emulation of older games, and also some newer indie games on the laptops. After that I have a "gaming" PC (nothing amazing but it does enough for me) for more current games, although I'm finding that I don't turn that on as much as I'd like to, lately. Then I have a handful of less-old consoles that my other devices can't emulate well, but I can't even remember the last time I used one of those.

Unfortunately, it is really buggy. A lot of trouble connecting. So, It is not perfect.
I play only on PC. I like mostly cRPGs and strategy games, so there is no need for console for me.
I used to be like you OP, PC-only gamer for a long while, but as I'm getting older (and got back into gaming a few years ago), I've mostly been using consoles or equivalents:
