There are a few games I play that have native Linux versions available (e.g. Warhammer Total War) and getting support requires you to run Ubuntu. Not the end of the world, but that plus some dev work was enough to get me to stick to it.

Linux Mint is Ubuntu

Not as far as the Game Devs are concerned. I was running Kubuntu and that wasn't 'supported' by them - only Ubuntu LTS.

You just install it. The debs work.
