Not sure what you need? The zoo advisors will tell you how to make the animals happy, and the customers themselves will tell you what they’re looking for, be it snacks, more animals, or anything else. For your customers, you can lay down paths to lead them around, then add food stands, amusement rides, even maps and trash cans. It’s completely free-form: Start with fences for your exhibits, then pick animals and give them toys, foliage, and anything else you want. An insidiously addictive simulation game, Zoo Tycoon allows players to create their own zoo, but not just any zoo.
