Pokémon Gold and Silver utilize the general design blueprint supplied in Red/Blue/Yellow -- Boy wanders the land to become the greatest Pokémon trainer in the world, with an archrival out to take your glory every step of the way. Both versions are identical in every way, except for the character images during battles, and the characters that can be caught in the wild, keeping with the "trading is necessary" design. The game has the familiar Japanese-style RPG engine, meaning top-down scrolling provides the perspective, and big-headed people inhabit the world. The hook in Pokémon is the fact that you yourself don't do your own fighting -- instead, creatures you capture in the wild supply the brute force of your battle skills. The creatures are Pokémon, and in Pokémon Gold and Silver there are exactly 251different species of these animals hiding in the game, waiting to be caught and trained. Happy hunting! (Amazon)
