FarmVille killer? FrontierVille reaches 5 million daily active players

It's hard to say whether FrontierVille will ever overtake FarmVille, but yesterday, the new pioneer-themed Facebook game from Zynga reached 5 million daily active players, according to Zynga. Not bad, considering the game launched on June 9.

The most popular activities in the game are customizing a spouse and raising a virtual family as well as the ability to 'hire' neighbors to help out on your homestead.
