Many gamers often condemn Activision for their annual release plans for Call of Duty . The belief is that this limits potential creative growth and critical innovation.

However, in response to this, Activision Publishing CEO Eric Hirshberg spoke about the benefit of having two talented development teams working on the same franchise. Furthermore, during his Eurogamer interview , Hirshberg said they're simply meeting player demand:

"The cadence of the releases seems to have found a nice equilibrium with people's appetite. There's demand and excitement each and every time out. Then people are playing throughout the year."

He added that more people are playing CoD in 2013 than ever before, and reminds us that the dual-studio approach leads to internal competition. While there are some definite similarities between IW and Treyarch, there are also different personalities within each group and as a result, this helps to battle stagnation. Said Hirshberg:

"Having alternating studios is one of the secrets to the franchise's success. You have different creative people who are strong-willed and have minds of their own. Everyone gets what makes a great Call of Duty game. Treyarch and IW are the masters, and have built this thing. So, there's a lot of common DNA from year to year.

But then people come in and want to top each other," he added. "There's some healthy competition. There's a desire within the creative team to not do the same thing and not be stagnant, the same way there is in the player community."

And besides, it's true that the release of a new CoD entry has become a "pop culture event," as Hirshberg claims. He gave the example of a lot of non-hardcore sci-fi fans going to see "Avatar" when it released, because it was, of course, an event. Well, I suppose you could look at it that way. When I do, I see what a shepherd must see on a daily basis from his protective position- lots and lots of fleece.

But when you successfully have the masses under your belt, that's always what you see. And the money sure does flow, doesn't it?
