Zoo Tycoon helps you gain an understanding of the habitats, food habits, living space of the animals. It is loads of fun to build a zoo & populate it with various types of animals.
The graphics are sketchy at best. Animals can eat people so that is also a fun part to explore when you tear down the cages. The game comes from developers with tycoon game experience, but it has no replay value & can get boring once you get the total hang of it.
