To alleviate that, maybe it would be a good time to fill in the empty years with more remasters, since these aren't unheard of but are seldomly done, and specifically remasters outside the Modern Warfare franchise. This is great news for fans who have become burnt out by the yearly Call of Duty releases, but it may also significantly impact the business model of Activision which heavily relies on these yearly releases.

Some believe the series will do away with brand-new titles every year and instead focus on making the next chapter even better. Right now, the Call of Duty franchise is preparing to undergo changes as Microsoft acquires Activision Blizzard.

However, Call of Duty: World at War introduced many elements that would become staples of Call of Duty, and it told one of the most interesting stories that the series has ever offered.

When discussing the best games that Call of Duty has to offer, it is seldom brought up as many look to its sequels as better examples of what Call of Duty can be. Many players believe that Treyarch's Call of Duty Black Ops series started with the aptly named Black Ops, but it was actually with 2008's Call of Duty: World at War.
