From my experience, I can install several repack without any issues on my Mint install (using wine). If you overwhelmed, the easiest way is to add the .exe of your game as non-steam game through the steam and the proton will handle the rest assuming you won’t find dependency issues, if you stumble across problem try to search protondb for solution.

Personally I run my games with wine because I couldn’t figure out how to make use of bottles and lutris (ye I’m weird).

EDIT: Also you can run your modded games on Linux, so far I have tried modded nfs mw (2005) with hard+, underground2, and new vegas, they are works like on Windows.

If shit happen, rtfm. gl op on your journey!

Woah, thanks for dropping the link. I did disable w10 update by modifying registry for each services which time consuming.
