I still shit my pants playing this game, and just as the starter of this topic said, it sure feels like they updated the AI even though that is not the case, which means that they made one hell of a job when they programmed this beast.
I'm still hoping that they will make some sort of sequel, but CA are busy with Warhammer: Total War now, and I remember that SEGA said that A:I didn't sell well enough for them to consider a sequel. Too bad.
