Activision: Call of Duty 4 was best-selling game of 2007

Much like the dim-witted kid you constantly taunted in kindergarten, Activision is having extraordinary difficulty making it past the number "1." Constantly cited in press releases, it appears uno is the only number the publisher cares to count on: #1 US publisher in 2007; a $1 billion dollar franchise in Guitar Hero; and #1 game in last week's Xbox Live Activity. Perhaps you too would be laughing all the way to the bank if you weren't such a mean-spirited brat in your early years.

Activision's latest claim to #1 fame is based on sales figures obtained from The NPD Group, Chart Track and The GFK Group, which label Infinity Ward's critically acclaimed Call of Duty 4: Modern Warfare as the best-selling game for 2007. The frantic first-person shooter is said to have sold in excess of 7 million units worldwide, a particularly impressive victory considering the game's relatively recent November release. Of course, those keen on the shooting of the aliens will recall that Microsoft claimed an 8.1 million sales 'splosion for Halo 3 earlier this month, bringing the title of "Best-selling Game of 2007 OMG" title into minor dispute.

We've contacted both boasters to clarify the figures ... just so we can be sure to stick the air pump into the right ego. Regardless, you'd best take this as a sign to start counting down the months until the inevitable Call of Duty 5 arrives. Let's just hope it's not a #2.
