Revamp Expansion Mod (RVE) A Supreme Commander 2 Complete Overhaul / Total Conversion Mod
I gave it 10/10 because I cannot think of a single flaw or bug with the mod and whilst I think it may give you a bit too much choice you cannot down vote a mod for giving you choice. Excellent improvement on the base game and with the rather poor engine it has to work with it does wonders.
