Zynga has revealed that FrontierVille has already attracted 5 million players. The social game company’s latest title launched just 13 days ago.

Descibed as a combination of Oregon Trail and FarmVille, the game includes new variables like wildlife encounters, varying weather, and vegetation growth. Players are also able to use a whole family of avatars and even help out at friends’ farms.

FrontierVille is available to play at facebook.com/frontierville/.
