Call Of Duty

Despite whether you are for or against the divisive game series, its presence and dominance of the First-Person Shooter genre can’t be ignored. Call of Duty has gone on to outsell every other shooter franchise and the numbers speak louder than the haters. Call of Duty overtook the first-person shooter genre many years back in 2003 with its first installment titled Call of Duty.

It is presently the industry's most popular shooter franchise, despite being chastised for its often-repetitive formula and a focus on the younger age as the series progressed. While it, like the rest of the titles on our list, has had its share of troubles, it is amazing, to say the least, that it has ascended to become the fourth highest-grossing series of all time. It's only natural that the top three won because they have a far longer track record.
