Yeah, the quality of Proton has in a way made it harder for me to decide whether to get a game or not. Previously it was no tux no bucks, but now I find myself researching whether a publisher has a history of doing shitty stuff about Linux. Turns out quite a few publishers who would never otherwise have made a Linux port have made a decent effort to keep proton compatibility with updates.
I will soon have to confront the brain tumor that I surely have, which makes me play League, as they are going to roll out Vanguard anticheat. I sorely wish there was an alternative with similar vibes, DotA is too sweaty for me and not as fun mechanically.
