Game: iPet

Virtual pet games were one of the first things to really take off on Facebook, resulting in a slew of mature, full-featured pet-raising sims like Pet Society. In light of that, it's a little confusing that a game as rudimentary as iPet even exists. iPet is Facebook virtual pet gameplay formula boiled down to the very basics with a rudimentary fighting feature attached. The variety of pets you can own is pretty limited (chicken or rabbit, basically) and while the decorating options are appealing, a confusing tutorial and poorly-localized in-game text make the game genuinely hard to enjoy.
