Is their fleet nomadic like thy say in all the videos? can you prosper without any planets?
You can, though you'll probably want to keep a few planets around just in case. But if you want you can live without any planets (after enough research of course).
Oh, and can there starbases jump between systems?
Not the Vasari Loyalists, but the Vasari Rebels can (they're a weird sort of diplomatic, hit and run hybrid).
