Yeah, you may be right storyline in MW series isn't that nice...(could anyone tell me a good story about world war II for example?)
The thing that I liked most in MWs isn't the story, but how you walk through it...the game hold me by pressure from the very beginning till the end.
@the_clown: what is clever AI for you? I mean by which parameters do you appraise it? For me AI WM is just great.
And yes, in WM you same as in Crysis and Far Cry walk from point A to point B, but it isn't that boring...
