Ken Thompson is one of the most influential unix of all time.

Cool story, but I already chose to believe Ken Thompson has no testicles some time ago.

As a Guix user, I recommend Ubuntu. If you stick with it, there are specific distros for gaming, but, Ubuntu has such a large user base it makes it very easy to get answers to questions that are specific to your distro. Ubuntu makes it easy to install nvidia and other ‘3rd party drivers’, it’ll just work. I do recommend installing software in the terminal, the Ubuntu app store I feel has some rough edges.
