Just to note: Most games will give you a minimum and most of the minimum requirements are meant to give you what the game will work with; however, most games minimum requirements only mean you can load the game with those specs, but for running the game properly you would need at least 128mb Video ram. And Zoo Tycoon 2 is one of those games that run much better on the higher video cards ramdac. My granddaughter has this game and her Geforce4 440 64mb card had to be changed out so she could play the game. We bought and installed a Geforce4 MX4000 128mb card and her game played much better.
