A capturing game
I used to play the orginal and number 2 when it first came out. Never knew they and expansions of the 2nd. Ever since i bought it, i can't stop playing it. I can play it for hours. It gives the player the chance to create a zoo from scratch, have what ever animals they desire in there zoo, and create it however they like, its brilliant. Being able to go into 'Zoo Keeper' mode and go in and care for your animals is capturing. Everything you want from a simulation game.
