Zoo Tycoon is a simulation of you being of course a "Zoo Tycoon". You build zoos insert animals, hire staff, put up stands, and much more. Zoo Tycoon won the 2005 Best Family CPU Game. Zoo Tycoon contains a Free Play section and a Scenario Section.
The Free Play Section is where you can make your own custom zoo at your own risk. You can vary the amount of starting money you receive to make the game more or less challenging.
There are three zoo sizes to select from: Small, Medium, and Large, and they determine the amount of land you have available on which to build your zoo.
