Game: Horse Haven

Horse Haven would seem to be a no-brainer when it comes to constructing a successful Facebook game, combining the virtual pet mechanics of raising and breeding favorite animals with farm sim elements of growing crops and managing livestock. Even better, Horse Haven focuses the whole thing around raising, breeding, and working horses. The basic idea is that you move from a starter horse to obtaining better horses, and then breeding new horses to increase your ranch's size and replace older horses that are retired "over the rainbow."
