The drama surrounding Modern Warfare development studio Infinity Ward and former studio heads' beef with their bosses at Activision, and ultimately the firing of the studio heads, had fans questioning if the quality of the "Call of Duty" spinoff would suffer. But with the game breaking sales records by selling 6.5 million copies of "Call of Duty: Modern Warfare 3" within 24 hours of it being released, the back story apparently didn’t matter. The Call of Duty franchise has cemented itself as an unmovable bastion of the video game world similar to Mario, Madden and Zelda. And "Modern Warfare 3" backs it all up.
