Pokémon FireRed and LeafGreen are the enhanced remakes to the original Japanese Pokémon games (Red and Green). Because of this, the game features the same Pokémon and storyline as the original games, giving them a nostalgic touch. They also feature many of the newer features of Pokémon, as well as an obvious graphical upgrade from the original Game Boy graphics. Pokémon Green had previously been a Japan exclusive, being replaced by Pokémon Blue in the US. Regardless, the Green remake was chosen for the US editions.
