Actually, the AI is not that good at all, matter of fact, they are rather passive. I've had one of my cities attacked the other day, and the besiegers just stood there, they didn't even attempt to advance towards the citywalls, they also didn't bother to bring siege equipment. Even after i sent my archers outside the citywalls, and started taking out their infantry units one by one, they made no attempt to advance. Only after i sent out my cavalry on a full charge, they responded, and by that time they had already so many losses, that their will to fight was broken very quickly.
