the only difference about it is it may include a Spinosaurus on the 'Extinct Animals' section of 'Ultimate Collection'.
However, recently they released an 'Ultimate Collection', which is basically all the expansion packs crowded onto one disk. I own all the expansion packs for it: 'Endangered Species', 'Marine Mania', 'African Adventure', and 'Extinct Animals'. The sequel, 'Zoo Tycoon 2' is based around making and sustaining a zoo and keeping all the animals in the zoo happy, healthy, and well cared for. It's the sequel to the original 'Zoo Tycoon' game. I am completely in love with this game! Has anyone else here played it? I'm sure you all know what it's about.
