The issue has never been that games can't run on Linux. It has always been a simple question of "will the games I want to play run?" More than ever, that answer is yes, but if your favorite game doesn't, or if you never want to worry about "will this upcoming (online) game let me play on Linux?" then you use Windows by default.
Like, I love y'all, but the Linux gaming community on Lemmy is kinda insufferable with the straw-man "people think games can't run on Linux" argument. That's just not the issue
