They do a decent job of piggy backing on Arch's work, and loading quite a few things OOB for gaming. That being said, I don't recommend them due to their instability and issues with the overall project (failing on cert renewals, their withholding of stable packages from Arch but allowing AUR access and causing breakage, poor release schedule, and cherry picking of newer packages for "shiny things" without the diligence to maintain their library compatibility, etc etc).

That being said, their theming and UI taste is actually really good. It was a much more robust project back in 2019 and 2020, but on the technical side they're lacking severely despite having great taste from a theming standpoint. They've fallen pretty far in the court of public opinion.
