Best one ever.
Call of Duty is one of, if not the biggest shooters of all time (Though I prefer Halo more). Modern Warfare 2 was the first Call of Duty that I played, yes even before the first Modern Warfare. I was actually so engrossed in the story I couldn't stop playing. I will admit that the game isn't the best game ever, but for the Call of Duty series it is the greatest. I would love to see this story turned into a movie sometime soon.
