Cityville.com

CityVille is a browser based casual social city-building simulation game developed by Zynga as an application for the social-networking website Facebook. It was announced on November 18, 2010, but the launch date was adjusted to December to allow Zynga to make adjustments to the game. The game attracted 100,000 players on its launch day making it Zynga´s largest launch ever at the time of its release. On January 2, 2011, it reached the most monthly active users for an application ever on Facebook, beating Farmville´s previous record although numbers may drop as its release date was exactly a month prior.
