Zoo Tycoon (2001)

This place is a real zoo--and you're in charge! Go wild running the most fun and beautiful zoo you can imagine. Care for unpredictable and untamed animals (and those are just the guests!). Plan wisely, because if the animals don't like their food, environment, or handling, they interact poorly with visitors, and unhappy guests means fewer dollars. Play smart and keep everyone and everything happy, and you'll be a zoo tycoon.
