If you make the Gaim Nomadic, just what that mean? I presume that they still start with a world, but cannot colonize? Can they still capture worlds? What, if any, advantages does that give them. Resources can be bought in by remote mining but research and intelligence need planetary facilites to my knowledge.

Couldn't a lack of expansion just be modelled under a scarity of compatible worlds - Hydrogen atmospheres aren't the most common under this mod.
