I've been playing a lot of Zoo Tycoon 2 lately. The graphics are pretty amazing and you can travel through the zoo with a first person perspective. That's a pretty cool function and the graphics stay detailed, clear and smooth. I'm not sure they've worked all the kinks out as I have been stuck in the same scenerio for a long time now and I don't think it's my fault. But I just keep on playing. Of the Tycoon games, it's right up there with Roller Coaster. I think the rest are pretty crappy (though I haven't played very many of them so I can't back that up).
