CityVille

CityVille was released sometime December 2010. Zynga, creators of FarmVille and many others facebook games, is on the right direction. With the release of CityVille, it has surpassed the amount of online players/users in a single month of release. About 60 million that is. CityVille is/or will probably be the best asset Zynga has produced, although, now with the release of RewardVille, I think Zynga may make a huge bang in the social network entertainment scene.
So now is the time to play CityVille and become part of one the biggest, fastest growing online social network games on the internet (CityVille).
