An all-new Pokémon adventure,Pokémon Goldis a  sequel toPokémon Red,Pokémon Blue, andPokémon Yellow. Over 100 never-before-seen Pokémon have  been added, just waiting to be captured. But that's not all: when first run, the game asks  you to input the local date and time. From then on, night and day in the game follow  night and day in the real world. Some Pokémon can only be captured when the  sun is out, while some can only be captured under the light of the moon. And everything  is in full color, which is sure to delight Game Boy Color owners (the game will also work  with standard Game Boys).
