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.
As people are most likely aware, Sins got an update recently to version 1.84. Thankfully, in English this just means that the Steam and GOG versions are now the same. So if you want to play SoGE with the new Steam version of Sins, apply the GOG/1.84 patch which is avaliable here: Moddb.com
On another note, pictured here is the Maxilipede, the CIS' new envoy which will replace the Hardcell in the next major release. Model/texture by Warb_Null.
...No more Hardcell? :(
