Same mod, different name, The Galactic Empire, the Rebel Alliance, the Black Sun Pirates, and the Droid Empire, fight for control of the galaxy.
Need extra firepower in GC or skrimish? Then how about recuriting a Mandalorian Fleet. Got the idea from the now dead mod Era of the Mercenaries, the difference is ETM had Merc fleets instead of Mandalorian fleets. Both the Empire and Rebels can build this fleet. Also if you have control of Mandalore you can recurit Mandalorian milita squads and Canderous Tanks for land.
