Some info from the review: "If you love animals and zoos then Zoo Tycoon 2 is a must for your collection. The world's most popular zoo simulation game has been a hit since its first version for the pc which was launched in 2004 and since then several versions have followed. Due to the popularity of Zoo Tycoon for the pc Nintendo decided to try its luck by producing the game for its Nintendo DS, the first DS version was then released in 2005 and was again equally a hit. Zoo Tycoon was not only produced as a game for players but its format also proved to be useful for children when being used as an educational tool. Yes, I said educational tool."
