There's not really much more to say, is there? Publisher Activision notes that the 8 million folks dabbled in Modern Warfare 2 during its first week of release, which outnumbers basically every major organized army on the planet, Activision gloats. Obviously, the publisher forgot to factor in Antarctica's Grand Army of the Penguins' Republic, currently numbering in the tens of millions but, in the interest of celebration, we're willing to overlook this oversight.
On a side note, this is good news for Electronic Arts, because there's obviously a market for these newfangled war games.
