1. CityVille
CityVille, made by Zynga, first came out on Facebook in late 2010 and was later released for Google+ on September 26th of last year. CityVille gives you the ability to become your own mayor. You start out with a small town that you have to build into a sprawling Metropolis.
Players have to perform tasks including: farming, construction, and collecting rent which uses energy points that increase every time you gain a level. The social aspect of this game is the basic visit your friends and do stuff for their city, farm, and so forth. Currently, there are 90 levels that you can gain in the game.
