Official Product Description"In Zoo Tycoon, you'll be challenged to build the most healthy and vibrant zoo possible. With an easy to learn interface, you can begin planning your strategy and building your ultimate zoo the moment you start the game. Which is a good thing since you'll need to build, manage, and maintain a zoo with over 200 animals, exhibits, and zoo materials. Plan wisely, and all of your animals will be happy. Plan poorly, and those lions, tigers, and bears may find a new found interest in you!".
