Had this one lying about in the great big vault of unused stuff. Originally wanted to make a massive, procedurally generated space exploration game with orbital mechanics, customizable ships with interiors and fully explorable planets, as well as modular surface structures, and all multiplayer. maybe I aimed a bit too high. Got a cool planet maker though! The sea levels are usually just a little too high or too low, and there is a glitch where some small planets get a giant pillar into space.
