Inspired by Traveller, this rulebook feels more like its supplement to me than a game of its own, despite a lot of tasty details that bring more realism to the tabletop Space Opera. Problem is, I don't believe in narration-driven games nearly as much as I do in OSR.
Anyways, some techniques of Diaspora are of value, namely cluster creation, social and platoon conflicts resolution mini-games. That may put those Fudge dice to action once again! Also, I respect all projects with a public SRD.
