Fedora, it fucking slaps and worked right out of the box. I'm using it for work and play on my main rig! I dual boot for some very specific hardware things that are not normal, but other than that it's been seamless! When I booted into Windows 10 again, they auto installed copilot... Glad to be done with this crap.
Lutris is an application where users commit installation/setup scripts for popular non steam games to manage setting up the environment to run them in.
Bottles is a similar program but the user is responsible for the setup process (that said it isn't completely unguided- usually making a new bottle, picking the gaming preset, and then running whatever installer you have is enough). Underneath the hood they use largely the same compatibility layers/technogies to run windows applications, but learning a little bit about bottles will help you work through scenarios where a lutris script doesn't exist or has been abandoned.
