The social aspects are both interesting and kind of weird. You can chat with patrons, befriend them, aid them in flirting, and make them happier attendees of your park. The odd thing is, some of the conversational choices are normal, but many others consist of spouting random factoids to people.
It's almost like you're that kid from Jerry Maguire constantly saying things like, "Hi! How are you? I'm the manager of this park. The human head weighs eight pounds!" And while we were amused to learn that the fly is the most dangerous animal on Earth and the moon has moonquakes, it's almost impossible to guess what a guest's reaction to any particular comment is going to be.
The PlayStation 2 and Xbox versions of the game are identical. While the voice acting and music enhance the game's playful tone, the graphics… well, that's another story. To be honest, the visuals could be mistaken for a PSone game with smoother edges. It's probably a symptom of all the computing going on under the hood (tracking the emotions and activities of each guest in the park), but it's nonetheless pretty unimpressive. On the plus side, you're not losing out if you have to choose one version instead of the other. If you're into it, you should just go with the system you have or prefer.
