Activision's long-running first-person shooter franchise has been pushing forward with annual releases for over a decade. Ever since Call of Duty 2's release in 2005, a new Call of Duty title has launched between October and November of every year since, now spanning three console generations. Generally speaking, Call of Duty has seen renewed success every year in succession, even if certain entries were received better than others by critics and hardcore fans. However, it's only been a recent and more significant trend with the last two annual entries where the annualization of the franchise is generally starting to impact the reception of the franchise.
