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 1.86 and, with or without, all DLC. Rated #6 players choice in MOTY 2014. An editors choice in MOTY 2015.
The extra galactic Yuuzhan Vong are not nearly as economically focused as the other factions, in part due to their very nature of not being a natural part of the galaxy and it's trade routes.
Regardless they are a no pushovers, for they are advanced in one area the rest of the galaxy lags in, bioengineering and biotechnology. With research they have the fastest ship and structure production of all factions in the mod, thanks to their methods of growing rather than constructing.
They also regain 50% of the value of all destroyed capital ships and structures, recycling their carcasses to create new materials.
Further, their mastery of darkspace is something to behold, for with proper research no ship can hope to keep up with a Vong vessel in hyperspace, not even the Millennium Falcon.
