Zoo Hospital review at IGN.

"Animals are the best way to secretly educate children. Those saps never even realize that the tidbits of information they learned about adorable Pandas are actually real live facts! Animals also serve as a great way to sneak education into video games. Torus Games has combined the natural appeal of animals, and the popularity of doctor games to make Zoo Hospital. Of course kids will quickly catch on when they realize the game has barely any game at all, and all that's left is a digital zoo map."
