I installed Debian + KDE on my mom’s laptop. She hasn’t had a complaint since. How tech-savvy is she, you ask? I’m sitting with her right now, so out of politeness she put on headphones to watch her favorite soap opera. Mind you, the headphones weren’t plugged into the laptop. She was sitting there, headphones on her head, sound coming through the speakers, watching her soaps like this is how it’s meant to be done.
I don’t think I’ve come across any that I wanted to play that don’t work at all.
The main ones that don’t work are the ones with kernel-level Anticheat. The one exception is Easy Anticheat. They made a way for that one to work.
So that will mostly be multiplayer games like COD, Destiny 2, Overwatch, etc. And EA is making a push to switch their games to their proprietary anticheat which doesn’t work on Linux. So I think Battlefield is now on that list as well.
If those games aren’t the types of games you play, then you should be mostly fine.
