The Smurfs & Co is a new social network game that allows anyone, anywhere to play as a Smurf, allowing you to build up wondrous towns to uncover special ingredients Papa Smurf needs in order to create a magic potion to erase Gargamel's memory.
If nothing else, Playdom's Gnome Town is notable for the absence of a feature. Yes, this is a Facebook game with no energy system, so you don't have to worry about ever running out.
