I have all ZT2 expansion packs except for Extinct Animals (dinos just don't do it for me) and I have to say that the Endangered Species expansion is the best. The scenarios are far better than the ones added with African Adventure and Marine Mania because they are more challenging and interesting. The new animals are a lot of fun and I think you get the most for your money, compared to the other expansions (again, I cannot speak for Extinct Animals). I love it!

I bought this game for my son and he loves it (he is an animal lover and a Zoo Tycoon fan). Just like the base game Zoo Tycoon 2, the features are easy to use. New trees, buildings,animals, bridges and Jeep tours are just the beginning. My son and I both love the endless play and possibilities. I would say that if you have Zoo Tycoon 2, then you need all the expansion packs. But this expansion pack is the greatest in my opinion because of the elevated bridges.
You can't go wrong with any of the Zoo Tycoon games. Kids and adults love them.

My nephew loves the Zoo Tycoon Games. He loves the added animals in this game and also loves the Sky Ride you can make to go around your zoo. This arrived quickly and has been working well so far. Thanks

I got this game for christmas. It was actually the only computer game I got for christmas. What I like to do is mix dif herbivores in the same exhibit (e.g. Savannah herbivores together). You get higher ratings from the guests if you do it that way. Another game I recommend is The Hobbit. Except you fight the animals instead of taking care of them. All in all, this is a terrific game!

This expansion pack is a great addition to the original Zoo Tycoon 2 game. My kids love to play it, and so do I. I only wish it had more new campaign/scenario games.
