Always online with kernel-level anti-cheat has a tendency to not work, but that is probably a red flag since there are thousands of different games you can play that don’t snoop around ring-0

It's not a simple one to one. Everyone's use case and experience is different. Don't get me wrong, I'm all in on the FOSS train and I don't approve of Microsoft's direction with Windows but it's still a consistently hassle-free experience compared to Linux for people who just don't wanna deal with distros, terminals, repositories or compatibility layers.

Well done mate! You are not alone!
