Haha ridiculous.
My 10 year old sister is competent in CoD. It's ridiculously easy to play, and, like I said, is a game of whoever sees the other first. Once you get shot at, there's no chance of saving yourself.
And why would you make-or-break the game based on the storyline? Online play is far away the breaking point for first-person shooters. But I will admit, CoD's storylines are slightly better than those of Halo.
