Hold on, is the AI like this in the demo AND the game, or only the demo ?.
If it's like this in the game, then it won't matter if it's SP or MP, it will be the same, the player controls the Corps and if the individual units in those Corps act as the post above says then it won't play very well in MP.
I've spent my time trying to work the basics of the game without looking too closly at how each unit behaves but something has not looked quite right to me, having a hard time figuring out what that is, but it could be as descriped above.
Can it be an MP game anyway ?......you will need 3-4 hours to play it as IF you speed it up it spoils the whole nature of the game, it's made to be played at 60/60 or 30/60.....I'd not want to play it any faster than 30/60 speed, so MP games could take a LONG time.
