Bud, a good chunk of video games are easily playable on Linux these days. What you said was true maybe 4 years ago. There's only a minority that are multiplayer using anti-cheat and explicitly blocking linux compatibility layers.
I know i have more than 6k games on steam I usally play without any issues, what are you trying to teach me? :/ I'm having some issues... with low frame rates, poor game performance on my setup, thats all. I'm glad you are running it just fine.
Literally just add the exe into steam as a non-steam game, use protonup-qt to add proton-ge 11-5, set that as the compatibility layer for the game, then launch the game from steam.
