So I set up bazzite recently to play with it, and it has steam and lutris preinstalled which is nice. I installed the heroic games launcher flatpak from the discover app just because it’s been easier to set up games than lutris has been in my experience. You connect your other store accounts in the setup and you just have a list of games to click on and install, same way as you do in steam.

You can also install individual exe files in heroic pretty easily, I’ve had better success with games like king arthur legends rise by installing them in heroic as a custom game.

You may not need it, but you can also install ProtonUp-Qt if you need to install a specific proton version like Glorious Eggroll or something. It’s another point and click app that’ll do everything for you.
