Following the success of management games like Hasbro's Roller Coaster Tycoon, Microsoft today unveiled its upcoming zoo management strategy game, Zoo Tycoon, at the Gamestock show in Seattle. Players assume the role of a zoo manager, and they must oversee all aspects of the animal park, including construction of new habitats and the maintenance of a wide variety of creatures. The goal of the game is to build the ultimate zoo. The game features more than 100 types of animals, habitats, and building materials. We'll have more information about the game as we get closer to the scheduled release date this Fall.
