Well, since I haven't played neither God of War nor Shadow of the Colossus, I'll get to my most active playing ground: PC Games.

And in that, F.E.A.R. absolutely wins over anything else. It's the first game since Half-Life was made (with it's scripted mobile actions) that I've feel like "man, this is real!".

Computer enemies (soldiers) just act as if they were real. Running from grenades, flanking you, going through windows while shooting you, if you cover behind a truck they'll get to their knees and shot from under the truck, they cover with boxes and shoot without seeing (just the arm with the rifle shooting to where they "think" you are)...

You should play it and see yourself. It may be or not very advanced AI (I think it is), but the "feeling" is that they're real. Also it's a spooky game :D (first FPS-Horror title)

IMHO

Nintendogs.

GTA LCS for the PSP was excelent to me. I didn't notice any of the stupid bugs where people walk into walls etc, and seem to interact in a very natural way. You are right, canned animations can make characters seem inteligent. just my 2 cents.

I play mostly XBox/XBox 360 titles and I've been kind of upset with how poorly I feel the AI turned out for Condemned... having said that, the best AI for the games I've played so far this year is probably COD2, which is probably easier to program given the limitations on what can be done (compared to more complex games like RPGs).
