gaming on linux has gotten MUCH, MUCH better over the past handful of years. I’ve been on linux exclusively for 6 years and in that time ive gone from using Lutris for everything and only installing the few verified titles through fairly complex wineconfigs other people made, to a brief check of protondb before installing whatever i want from Steam and having it work out of the box. basically the only things that don’t work anymore are competitive anticheat softwares, like Valorant’s.
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).
