WoW is still king

This caught my eye today from an Inside Social Games post titled, Social Games Plant the Seed for Growing Online Communities:

According to WoW statistics, the average user spends 22.7 hours per week playing the game. Contrast that with a recent PopCap study, which showed that only 12 percent of social gamers are addicted enough spend 10 or more hours per week gaming. But WoW has about 12 million players, while FarmVille alone has 83 million monthly active users.

WoW’s 12M players pay them $14.99 a month while Farmville’s average revenue per user is probably closer to $1.50. That puts World of Warcraft around $180M/mo and Farmville near $125M/mo.
