Gaming in Linux is fine but it would be a crime to not mention, getting mods to work on Linux is still shit
Can you specify which games? I’ve modded plenty and it all still works as expected honestly
Oh my god, any game that either relies on nexus or a mod launcher, take your pick, I mean sure, it’s doable, usually if you have a windows pc to install the actual mods on and copy the file directory over, but that’s a slim chance that it’ll work, if you’re having no problems missing you’re probably playing Skyrim
Mods that are installed by moving files (which covers most games) work fine most of the time; you’ll probably need .dll overrides.
Mods that need certain libraries can be a hassle, or mixed bag (eg. RSMods for Rocksmith 2014 (CDLCs work fine though), RDR2 Mods based on ScriptHook.NET).
Mods that require a launcher are hard or impossible (pretty much anything on the Frostbite Engine. I think this is your best bet with it. Don’t know if OpenIV currently works on Linux or if you need a VM with shared folders to use it).
