Never got that one.
Although it infuriated me when people called it "Call Of Duty 5".
And I played Modern Warfare 2 for the first time a couple of days ago, and someone referenced how something in that game was "different than the first one" and I knew he was referring to Call of Duty 4, not Call of Duty 1.
He probably played Madden after that. And then watched his Dante's Inferno anime DVD "based off the epic videogame".
