Blue Monday have posted up a review of Zoo Tycoon in English and Spanish. Heres a snip:

    It goes without saying that in Zoo Tycoon we take the responsibility of managing a Zoo. That means you'll have to buy animals and keep them happy, and you'll also have to take good care of the guests. At first you'll have only a few items to accomplish your task, but as the game progresses, you'll discover a wide range of options to design and decorate your place. If you plan to make each animal live in its own habitat, you can browse through a complex database, containing detailed information about their characteristics and preferences. When it's time to think about your visitors, you have to remember they need to eat and rest to be satisfied. It's not really hard to do all this.
