Just like Pokémon Gold and Silver, Pokemon Crystal utilizes the general design blueprint supplied in Red/Blue/Yellow: Main character 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.
