I’m really lucky that I avoid anything that has anticheat. Not because I’m a cheater but because all the slur-screaming 12 year olds and my own fear of getting addicted to MMOs if I ever gave them a try have mostly dissuaded me from anything with online multiplayer.
Which means most of my games are Linux-compatible and I have no gaming group I’m giving up by making the jump :D
Saw something on programming.dev about some extra telemetry Windows 11 was adding or something like that? I forget. It was definitely something I think is bad, that people on programming.dev also think is bad. Then, despite having done registry edits and everything else I could think of to turn off auto Windows updates to make sure I would not get the bad new feature added in an update, my Windows 11 computer auto updated anyways. Got mad, wanted to switch to Linux, asked !linux@programming.dev for help, and finally did it four months later, a few days before the new year started.
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.
