It's beginning to look like not as many gamers are answering the "Call of Duty" this year.
Though publisher Activision Blizzard has revealed very little sales data for the latest installment of the most successful franchise in the console video game business, mounting evidence indicates that this year's "Call of Duty: Black Ops II" is selling fewer copies than last year's "Call of Duty: Modern Warfare 3."
On Nov. 16, Activision reported that "Black Ops II" grossed more than $500 million worldwide on its first day. For the past three years, however, Activision has reported day one sales information only in the U.S., Canada and the United Kingdom, making this year's data difficult to compare to past years.
In addition, over the past three years Activision has reported worldwide sales data for its "Call of Duty" games over the first five days. This year it did not.
