"Only for zoo tycoon collectors"
Note: This game Requires Zoo Tycoon 2 or Zoo Tycoon 2 Zookeeper Collection

This expansion gives a new challenge for players with the need to keep tanks clean and the option of traing animals to perform tricks the price

currently the price around $20 is a little too much for its contents unless you are a big fan of the series.

"Great fun"
I purchased this expansion pack for my husband and two boys, ages 7 and 11, after they had so much fun with Zoo Tycoon 2, the dinosaur pack, and the extinct animals pack. They have really enjoyed this game, and have had a great time incorporating the aquatic animals into their zoos. I recommend adding this to your collection, no zoo is complete without killer whales and seals! And you can swim with the animals as well!

"A kid's review of Zoo Tycoon Marine Mania"
Marine Mania is a well-developed game. I don't have all the zoo tycoon expansion packs, but I have marine mania and endangered species. This is my favorite game out of those. I like to train the animals and put on shows. But I don't play it that much, because it keeps crashing on my only 4-year-old PC! But overall, I love this game! It probly crashes because the game is too strong and complicated for my computer. Anyway, I love this game!

"Great expansion game"
I originally bought Zoo Tycoon 2 (Zoo Keeper version with two expansions)for my daughter and I. It was so great that we got the Marine Mania expansion as well. We were not disappointed. The entire set is a fantastic game as well as a learning experience. Although the game recommends ages 10 and up, my daughter is six and would play this game all day if we let her. Marine Mania has great new features such as tank walls and training marine animals for shows. The game and all the expansions are rather pricey but I think it's worth the price.

"It is interesting"
It takes a long time to train an animal. Even to hire it done. I love the items you can purchase. It is fun, just takes a while to train.
