Virtual pets have moved on since Tamagotchi, the robot pet that dies if you don't feed it. Creature Park, an online game developed by Ingeeni Studios in Cambridge, Massachusetts, allows players to buy pets and place them in a virtual house. The pets can move, sniff each other and mate to produce offspring, while large creatures will try to eat smaller ones. Babies can be kept and fed or sold on to other players.
