At their heart, most distros are approximately "made of the same stuff". There's differences in package management in the background (e.g. how the "software centre" works), but essentially the difference between a "gaming distro", "normal distro" and "creative distro" is just what programs are installed by default, and how a few things are set up by default.
Nothing stops me playing games on Mint (and historically, Ubuntu and Ubuntu Studio) - and likewise, nothing will stop you installing office programs, audio/video/graphics programs etc on something presented as a gaming distro.
