The reason for the insanely high CoD sales are because there is a huge group of people that only buy Call of Duty games right? I recall reading about that sometime ago or I'm just imagining it but I don't think I am. You have people that buy games year round that buy it but those are people that also buy Mario, Zelda, Uncharted, Gears, Halo, Resident Evil, etc. Then there is I believe a separate group that just buy Call of Duty and play that and nothing else (maybe Madden) and then jump on the next one that comes out. Is that what we're looking at here and perhaps why no FPS can dethrone it and why it's foolish to try? Since it simply isn't normal game buyers playing the game but Call of Duty only players and you can't convert those or get them to try other games because they have no desire to play anything else. Didn't this used to be the case with Madden in the past or maybe still is?
Is this the wrong way to look at the CoD sales?
