Pokémon Blue Version

Pokémon Blue is the third Pokémon game in the core series, released as a small revision of Pokémon Red and Green, which were released in the same year. Thus, it was the first standalone version of the core Pokémon series. Among the various fixes in the game were an improvement in graphics and sound, as well as the elimination of several known bugs that had appeared in the original two games. Outside Japan, the graphics, game engine and script formed the basis for Pokémon Red and Blue, while the lists of wild Pokémon and game-exclusive Pokémon were adapted to Red and Green.
