i've had the game for about a week now and i get to play about 2 or 3 hours a day-- i've only done single player and it took me about a full week to REALLY understand what is going on with this game and i'm still learning-- this is an amazing game! i'm 53 years old and i haven't had this much fun with a game since the original Total Annihilation!-- the depth is absolutely incredible-- hat's off to the developers-- they got an old man who had given up on PC games back in the fight!-- Fond Regards, shadow
