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 1.90 and, with or without, all DLC. Rated #6 players choice in MOTY 2014. An editors choice in MOTY 2015.
Almost everything about this mod is spot on. The ships look fantastic, the sound effects/ voice overs are wonderfully authentic, and I can build a friggin' Super Star Destroyer. Honestly, it is nearly everything I wanted in a Star Wars mod for Sins.
As others before me have noted, the biggest drawback is the size of the ship models. Every single ship, with the exception of the Super Star Destroyer, feels so tiny. I do not get a sense of power from a micro-machine sized Star Destroyer. If the size of the models were scaled up ~200% or so then I think the mod would be, basically, perfect.
As a side note, I rarely played vanilla Sins so I have no opinion on the economy changes of the mod. I think the economy works pretty well. By late mid-game I am basically flush with cash and have no real limits on my spending.
