The genius of simulation games have often left our testers in awe with comments like "How do they do that?". The level of AI sophistication, or artificial intelligence, is so advanced in this latest incarnation of Zoo Tycoon that you will believe that the successes, failures and catastrophes that befall your simulated domain are really happening. Whether its disgruntled employees, lackluster ticket sales or escaping animals you will be tested again and again to prove your mettle. The graphics might be the most noticeable enhancement, and there is a really nice tour through the zoo that will knock your socks off.
