Not gonna lie, you probably will get lots of hate, but fanboys will be fanboys, just ignore them.

In any case, this probably means you enjoy multiplayer AAA games, since as a general rule those are essentially the only ones that don't work out of the box nowadays. Unfortunately those games are actively trying to detect if you're using Linux to prevent you from playing, and if you had managed to play them you could have gotten yourself banned (like some users reported with some games).

The other large cause for problems is the wrong drivers or not using the correct GPU in multi-GPU systems. If you were having issues with games everyone else was playing in Linux this is likely the cause.

You choose Mint, which is an excellent beginner friendly distro, and it's very close to Ubuntu which is the de-facto common ecosystem agreed to use. That discussion about having a common ecosystem was over a long time ago, it's Ubuntu. But that doesn't mean you're stuck with that, it means that developers can focus on targeting one OS, and the community will figure out how to get it working in other variations when it doesn't work out of the box. If it requires changes from the game we usually submit a bug report explaining what needs to be changed and why. But for you, the end-user, just having Ubuntu or something similar like Mint should get you a good experience since games are tested using that.

At the end of the day Linux is not for everyone, sometimes you want specific software that is not made for Linux and that's okay (okay on your part, fuck the companies that are actively making software unusable on Linux).
