Very nice work. It would be cool if different research made changes to vehicles and so on. Like the railgun having a special looking raildriver line instead of a normal turret and so on. Also more variation on the sound side would be cool but a bit hard to make/get. Such as special engine sound for all the engines and so on.... maybe even different looks for the exhaust systems. The sound side really does alot, as I was tired of the regular sounds especially the vehicular machineguns and turrets + the smgs and HMG... SO I replaced them with some badass sounds and that really made it more enjoyable.
those are so nice shinzon.... customised tank models (with rocked pods on them if they had rockets) are the inevitable conclusion for empires.
