I did see a thread, but it's a few years old.
Turns out there's a lot more of these things than just "steam deck".
What do I even look for? Specs like a PC?, are there certain programs that only work with certain ones like console?
I have an Xbox series X for modern games, my laptops are trash, and my desktop is nice for 10 years old, is not in a good place for constant use. I'm looking/hoping for something I can play older, like say 1995-2015, computer games on easily and not in my living room. City builders, maybe old single player FPS, actually everything would be single player.
Should I even be looking at steam decks for this?
