A month ago, Electronic Arts purchased several domain names for SimCity Social. The publisher officially announced the Facebook game at their E3 press conference today, as well as Madden NFL Social.
The game, which was co-developed with PlayFish, allows players to build their own cities while living in other people's. The game basically resembles SimCity 3000, while giving players the option to either be a benevolent mayor, or an "evil" one.
Players who "like" the game on its official Facebook page will get bonus items. The game will be launched "soon".
