When it comes to social games, Zynga is the undisputed king. But, when it comes to second place, it's not so easy to say -- the competition is stiff. Yet, today German social game developer Wooga has (at least for the time being) overtaken EA as the new deputy in town. Wooga is now seeing over 35 million monthly active users engaging with its social games, compared to EA at just under 31 million, Playdom at 30 million, and CrowdStar at 22 million, which rounds out the top 5, according to Appdata . Wooga doesn't get nearly as much attention as Zynga or EA, with the former steaming towards its IPO and the latter an industry veteran that just so happened to acquire Popcap for nearly $1.3 billion last week.
