It’s not really a meme. It’s from c/196, where the main rule is that you have to post something before you leave, hence why everything is named rule. If you block 196@lemmy.world and 196@lemmy.blahaj.zone that should deal with almost all of the rule posts.
You can run most games on Linux, you just have to enable proton, the steam deck uses a custom version of Linux by default, so at minimum anything marked as playable will work on Linux.
Also I never had to deal with drivers at all when setting up linux, but I’m not sure if that’s normal, I’ve only used Linux mint, which was pretty easy to set up.
