From the PlanetXbox360.com feature article: "Since Call of Duty’s shift in direction away from WWII, each release from the Modern Warfare series has had something to prove. Call of Duty 4 had to prove that the contemporary setting would work within the context of the series. Modern Warfare 2 had to prove that Infinity Ward was capable of expanding upon the previous title and outshining the trending competitors. Modern Warfare 3 has more troubling circumstances surrounding the game’s release, but surprisingly, consumers are not as worried about these issues as one might think. The development of Modern Warfare 3 was interrupted by the internal turned legal problems between Activision and former Infinity Ward heads Jason West and Vince Zampella, which lead to their departure and resulting legal actions. The awareness and level of concern from consumers regarding this story are not all that high though."
