Released on Dec. 8, Pet Shop Story builds on the success of previous build-your-own shop games, and moving the genre into the pet store. You can create a pet store with all of your favorite pets, or if you feel like it, create new species (I thought it was cool to create a flying dog by mixing a parakeet with a Labrador). The only limit to this app is your imagination. You can visit your neighbors' pet stores and invite your Facebook friends to play along with you, as you build your menagerie. The graphics are fairly good, although not as good as advertised, and there are updates every week with new types of pets, decorations and different ways to combine the pets.
