The reason I started playing on PC is because I want the best experience for each game, and ability to play most of them. If I have to ignore certain games that don't support Linux, I lose that.
Mad respect to those of you that prioritize software freedom and Linux support, but that's not me.
I ignore certain games that don't run via proton, because those certain games typically dont run because they have invasive and unnecessary DRM or Anticheat thats more malware than anything useful for protecting play.
Which I wouldnt buy or have on my computer on windows, much less linux, anyway. So nothings lost.
