The CityVille Facebook game by Zynga, which is launched less than a month ago, has become the world’s most popular game, nabbing the number one spot from Zynga’s own FarmVille social gaming.
According to AppData, CityVille just reached 65 million monthly active users, while FarmVille has 57 million users.
CityVille, launched Dec 2, is a city simulation social game. You can build stores and operate franchises in your friends’ towns. While CityVille is free-to-play, users can spend real money on virtual goods to enhance gameplay.
It is estimates say that Zynga has brought in between $500 million to $700 million in revenue this year from the sale of virtual goods, NYT reports.
