Thats because of the HUGE increase in user base.

 

But how many Wii sequels have outsold their Wii originals? I doubt Mario Galaxy 2 will out sell Mario Galaxy 1.

 

 

 

also...GTA 3 outsold 2... but it's quite obvious why. It's a completely different type of game.

 

 

Can anyone explain the huge jump in COD sales?
