What is the difference between Pokmon Red, Blue and Yellow?
The only difference between the Red and Blue versions is what Pokmon you can find in the game. The story, bosses, item locations and gameplay are identical. The Yellow version, however, has a slightly different storyline which follows the Pokmon cartoon show more closely. To collect all 150 Pokmon, players must use the Game Link cable to trade Pokmon with a friend who has a different version of the game.
