The gaming industry can be one of the most lucrative in the wider entertainment space, but just like movies and TV shows, for a game to really earn the big bucks it needs to have mass appeal. While there are plenty of gaming franchises that have a pretty big following, only a handful are on the same level as Call of Duty, a series that has managed to retain its popularity for two whole decades now. Every year, a new Call of Duty rolls around, and every year the money rolls in, with the same audience knowing what it's getting into. Call of Duty is like a form of comfort food, but that might no longer be the case with Call of Duty: Modern Warfare 3.
