Well, Nothing stops us from making it a part of an even greater campaign in which you're conquering a region of space - all that is needed is star maps with warp connections and a set of rules for playing in this dimension. Though there are no models here except maybe for fleet markers, this part of game gives you a grand scale to the conflict, and a lot of fluff to fuel the lower levels with importance - We've got to control that system for it has several warp connections to adjacent systems and open our way to conquer the new pocket of systems, colonise them, get more resources and kick .....!
