I enjoy retrogaming as much as the next guy but it makes the Linux community look detached from reality to suggest that video games are a commodity. People want to play specific games. If pleading with people to be satisfied with native offerings was a winning argument it would have won twenty years ago. Emulation is an incredible experience on Linux but to do it legally requires you to already own the proprietary rom and bios almost without exception, which I notice is conveniently omitted from the discussion.
