Unlike total war battles where your biggest armies will consist of a little over a 1000 men UGG has entire corps of men fighting in a single battle. The battle stages are great as it gives more life to the game as you brigades lose men and the loss of critical points can effect the out come of the next battle. I think expanding this formula to a overall civil war campaign would blow away the competition completely.
P.S. Im new to the UGG forum and am not aware if this is already planned or has already been suggested before
