Zynga’s Empires & Allies does direct combat with Kabam’s Global Warfare on this week’s list of fastest-growing Facebook games by monthly active users. Digital Chocolate’s competing strategy game, Army Attack, drops out of the growth race with a steady 5 million MAU to its name.

It may not be the end of the strategy Facebook game wars, however, as Playdom still means to release what sounds like a competing game called City of Might. A glance at previews for the game make it look somewhat more like Global Warfare than Empires & Allies, however.
