Steam is absolutely the EASIEST way to run games on Linux.

It abstracts Wine, Proton and all the other dependencies so you don't have to think about it much.

You just install it, download and play exactly the same as you would on Windows.

There is also Heroic launcher, which is a similarly streamlined experience for Gog. (And Epic and Prime Games, if you're into those)

Steam is honestly your best shot for getting a game to run, they've worked pretty hard on their compatibility layer.

I've been using Steam on Linux for a few years. Check out Proton DB for game compatibility.

Yes Steam is the main tool Im using to run games, even non-Steam games.

Bazzite also comes with Lutris which will set up some wine wrappers for you, which work fine, but Steam gives you things like Steam Input. I’ve never seen a controller mapper as good as Steam Input.

I don’t know what the performance comparison between Valve’s Proton and current FOSS variants of Wine is.

My current workflow is to use Lutris to manage games from GoG (no GoG Galaxy on Linux). I install them via Lutris, and then add them as non-Steam games to Steam, which lets me use Proton and Steam Input. The only game I’ve installed so far that I’m not running through Steam right now is Minecraft.

The only loss is I can’t run Destiny 2 on Linux due to its invasive anti-cheat, but I was on the verge of quitting D2 anyway. Note that some games with invasive anti-cheat can still be run through proton, it depends on the specifics.
