I've been wanting to play a game set entirely within a large, highly populous star system. Particularly, one with several jovian planets with moons, a couple asteroid belts, and several earthlike or teraformable worlds. Ideally, this would be a four-star system.
Unfortunately, simply generating new systems until something appropriate pops up would take a very long time indeed- I've tried hundreds of random systems only to find three or four quaternary stars, and generally these systems only have a debris field and an uninhabitable planet.
Is there a way to edit the probability of various star/planet types in the database? Failing that, is there an easy way to simply dictate the contents of a system, including the generation of a few hundred asteroids?
