SoGE is a Star Wars Total Conversion for SoaSE: Rebellion with it's roots in the Homeworld 2 mod Star Wars: Warlords which features the two primarily sides of the Galactic Civil War, the Clone Wars, and the Yuuzhan Vong War. The current public version works for Sins of a Solar Empire: Rebellion 1.80+ and all DLC.
Very good mod for SoaSE. Massive fleets of Star Destroyers squaring off against the rebel scum? That's what this is all about. Some of the units don't really scale perfectly (an Executor class should not be brought down by three MC-80s and a few wings of fighters), but very well done!
