A Tamagotchi is a small alien creature that hatches from an egg. Once it is "born," it is up to you to raise it properly by feeding it, cleaning it and playing games with it. Depending on how you raise the Tamagotchi, it will grow into one of several different species.
The Game Boy version expands on the options of the toy by adding more of everything: more food, more games and more detailed graphics. However, since it is unlikely that people would keep their Game Boys on constantly (the original hand-held tamagotchi units stay on 24-hours a day like a clock), other changes have also been made. You can save your Tamagotchis using battery-backed memory and raise up to three at once.
the game will be shipped out on Sept 10 thanks
