I understand reluctance to move because of ease of modding.
This does not answer it for all your games, but did you see this post about Morrowind/Oblivion/Skyrim modding on Linux? It might help for those at least.
I have managed to mod Dragon Age: Origins successfully with the help of winetricks and/or protontricks, I forget which one.
Oh wow, how did it do the latter!? (I’m technical than the average person, but half the time I feel too dumb for programming.dev, but I’ll never smarten up if I don’t stick around and learn, so…)
Also shifted off Windows 11 to Fedora. Well, at least, a modified version anyways—Nobara—on the suggestion of a user in the thread.
