Game Description:Monster Rancher is a simulation game where players create and raise their own monsters, then face them off against CPU and human-controlled opponents. For its first DS game, Monster Rancher uses the DS to create your new friends -- to build the stats and custom character abilities of your monsters, you can use the stylus to draw patterns, you can speak into the microphone, or you can insert a GBA cartridge into the game slot Game Boy Advance cartridge slot for even more monsters. Once you've created a monster, you have a number of ways to train it. New to the DS version is a board game which you can play to raise your monster. Alternatively, you can select training options the old fashioned way, from a menu. Eventually, you'll be able to merge multiple monsters into a super monster and beign climbing the ranks of a monster tournament.
