Zoo Tycoon Too

This from a review of the pc game "Zoo Tycoon 2" (gamespot.com):

"The sequel to Microsoft's surprisingly successful Zoo Tycoon makes some real improvements to the [life sim] formula established [by] its predecessor, but it's still probably best suited for parents looking to play games with their young children. Zoo Tycoon 2, like the original game, lets you build a zoo full of different animal exhibits and challenges you to make sure everyone in it stays happy.

"If you keep your animals happy, they'll remain healthy and entertain your guests. If you pay your staff fairly, they'll remain happy and do an acceptable job of keeping the park clean and the animals cared for. And if you keep your guests happy, they'll be more likely to make donations and purchase refreshments or souvenirs.

"Succeed at everything, and you'll make you enough money to stay in business, research upgrades (like additional shelters and animal toys for your exhibits), and expand your park."

Sounds a lot like the real thing.
