chimera is is a near drop in replacement for steam os built for being a gaming first distro. it isn’t great if you want to do many other things with your desktop but works really well if you only want to game.

I installed the first one but never got around to paying it cause I beat the game so many times but it’s been forever since I played jak 2 or 3 so I’m much more interested in this.

holoiso is great for a gaming focused distro, essentially the steam deck os but you can install on most devices, but may not play so great with Nvidia cards.

geruda Linux is an arch based distro that is built with gaming in mind and has many flavors of desktop environments to choose from.
