multiplayer campaign has some things that need to be worked out, such as if you are playing with a human ally and you wish to fight a battle on your own vs the AI, you are forced to autocalc it or let the human ally command the enemy forces. This is pointless, as they will be trying to do badly to help you both. They really need to redo the multi campaign system to have a movement phase simultaneously and then a battle phase the same. Autocalc-ing battles is just stupid and rarely worth bothering with. It's hard to understand what I mean unless you have tried to play a co-op campaign in multiplayer. The rest of the game is superb though.
