It surely is, it has also been really great to see the growing support for all those games over the last years. Sad to see some games still being borked with no valid reason (Pubg e.g., with the developers stating the game can run on linux with no problems at all, they still will block it bc they are scared of hackers or some other lame excuse).

Every problem I had playing games on Linux could be fixed by some kind stranger on there offering a command or sth. else (sometimes even stuff thats not related to linux at all lol)

Sure is! Almost every game that doesn't run well out of the box has a fix there.

There's also a great decky plugin that adds protondb badges and links directly to all your games on the deck. Really helps figure out any small tweaks you should use to maximize frames and will also mark games as silver/gold/platinum even if valve hasn't marked them as supported yet.
