Zynga Now Owns Four of the Largest Facebook Games

Zynga’s newest game, Empires & Allies, hasn’t exactly shot to the top of the charts, like CityVille, which hit more than 60 million monthly active users after less than a month. But after its fourth week, Empires & Allies has attracted 37.7 million monthly users to become the third-largest game on Facebook, reports InsideSocialGames.com, joining the other Zynga titles among the top four: CityVille (89 million users), FarmVille (39 million) and Texas Hold’em Poker (35 million).
