You should go in the topics above and post what will stay the same and what will change. And tell me how are you going to set the unit rosters - when game-play and history collide what will win (will there be 100 phalanx units or just 5 at most, actually).
I still don't have my own PC able to run 3ds max, BUT my gf does, so i will do units but it will be SLOW! I have more interesting things to do with her (sorry people, the bed beats the modeling on fun-factor ;) ). So, less speed, more quality (can't make crappy models in front of her, right) from me.
