Arch is pretty good, but it’s fairly easy to break it, if you don’t know what you’re doing. For gamers I recommend Bazzite. It’s an image-based fork of Fedora Atomic (Universal Blue). You can also try other ublue-based distros such as Aurora or Bluefin. Or Fedora Atomic flavors like Silverblue and Kinoite. In fact, you can easily switch between them without reinstalling your system. All it takes is one command, and ostree will do the magic.
