In the training mini-games, the player has to show tricks to different animals, ranging from showing the dolphins to perform acrobatic jumps to teaching the sea lions to play with a ball, while in the show the player has to decide which of the previous tricks the animals are going to perform for the crowd. Marine Mania was the first game in the saga to include mini games (Training and Shows). Since it was launched, Zoo Tycoon 2 has received three major expansions, one of which was Marine Mania, that allowed the player to manage an independent oceanographic institute or to add sea animals to his/her zoo, including belugas, turtles, manta ray and manatee. This game places the player in the position of a zoo director, having to take all the decisions that have to do with it: choose the animals, buy new buildings and, even, to hire zookeepers and other employees.
Zoo Tycoon 2 is one of the best economic simulation games that has been launched in the last decade.
