I remember those dark days when I would check winehq before buying games because I didn’t know if they would work in Linux or not.
I realized recently that I stopped checking winehq or protondb, because I implicitly assume that everything will “just work”. Hard to say when this transition happened, but it feels at least a few years old.
Looking at latest stats, the only holdouts appear to be those games that explicitly ban Linux users with some quasi-malware anti-cheat.
