FarmVille 2 Ain't No Game, It's the Ultimate Perpetual-Motion

In FarmVille 2, almost every element in the game is carefully designed to either keep players addicted, encourage them to spend real-world money or get them to invite their Facebook friends to install the app, too. The game works tirelessly to either monetize its users or expand its player base, which then feeds the game more players who can be further monetized.
