These sort of derivative distros seem to be aimed at Windows 11 Refugees.

I am not a fan of these derivative distros and I would always recommend using one of the mainline distros e.g Debian, Arch, Fedora etc.

I am using Debian 13 for gaming and the most difficult thing I had to install was a backports kernel which improved performance in some games, in other games it made no difference at all.

Installing Steam and Lutris takes about 5 minutes and it yet another distro for what amounts to installing some applications. I find the biggest issues on Linux gaming is the applying individual workarounds in Steam, and getting wireless controllers to behave properly.
