How about some coalition systems? Like Moscow, Kiev, St.Peterburg, let's see it's russia in the coalition, maby china so other systems like Beijing, Hong-Kong. (these are just names; im not suggesting to put ALL these systems). Oh, and a friend of mine Fire_tzunami found some nice ships models in the ,,Crossfire" mod found on www.lancersreactor.com. Why not put more ships in the game as powerful as the Barracuda (wepons 4-6) or who knows, not only level 10 ships :).
