Yeah proton still has a lot of limitations and workarounds to get many games working, so if you just want true plug-n-play you're not going to be satisfied with that solution.
Yeah, but I'd still argue that it's a lot better than nothing, and we have Valve to thank for making a lot of Windows games actually playable on Linux.
Of course it's better than nothing, at its definitely working OK, but gaming on Linux is still not quite good enough in terms of user experience. Average users don't want to, and honestly they shouldn't, debug just to play their game...
I am actually not sure this is correct. Voicing your opinion about wantong native support is a much better direction than trying to run a more and more accurate windows emulator.
