Elite for Emacs
I've always wondered if there is scope for a MMO version of Elite that is less ambitious (especially graphically) in some ways than the current Elite: Dangerous but still has the essence of Elite; I'm thinking 3D graphics with a retro vibe, maybe primarily text based menus for in-station activities (and certainly no desire for on-planet or first person shooter components). Even keep the generative universe of the original with its nutty planet descriptions.
