right, because quantity of scripts is the most important AI feature
I've always found you can see the true quality of the AI when you're dealing either 1 on 1 or against a small group of 2 or 3 with the difficulty cranked up.
When you're dealing with a large group there really isn't all that much strategy involved... it's usually run in and start smashing buttons. the AI's job becomes little more than making the enemies not move in exactly the same way.
When you're dealing with a single opponent or a small group of 2-3 you get to see how good the AI really is... can you easily predict their moves? if it's a small group do they share knowledge and if so do they share it realistically or does it work like a hive mind. And most of all can they analyze your own moves and stay one step ahead of you.
Dead Rising has hundreds of enemies on screen at once all running different AI scrips but it's also increadably stupid AI that consists of various flavors of
::if enemy is in range lunge forward and start biting::
Dynasty Warriors, Ninety Nine Nights and may other games also have massive amount of enemies with unique scrips... but I've never been terribly impressed with the AI in those games.
There are few games where the AI impresses me but when I crank up the difficulty I want to feel like the computer is genuinely outsmarting me, not just that there are more enemies that are more powerful and more accurate.
Splinter Cell is a spy game that relies heavily on strategy and outsmarting the AI... Heavenly Sword is not. If Krakker really wanted to impress he would have pulled an example from MGS4 seeing as it's a similar game.
...unless of course the AI in MGS4 really isn't all that impressive.
