I’ve been on Linux for 3 years now, and while almost every game works everytime, there are still a few that I either can’t get to run, or when I do they are unstable and require tinkering to get right. Catherine is a big one, that has gotten a lot better with more recent versions of proton, but still has glitches especially when transitioning from gameplay to cutscene.
What would you consider “a reason” then? The man had plenty of reasons.
