List of Pokémon games

1st (Gameboy) Generation

 * The Red and Green versions were initially released in Japan on February 27, 1995.
 * The Blue version was released in Japan on October 27, 1996. It featured improved graphics and sounds.
 * North America would get its first releases of Pokémon, the Red and Blue versions, on September 30, 1998. The North American versions were actually the Japanese Red and Green with the new changes that the Japanese Blue had.
 * On October 1, 1999, Pokémon Red and Blue were released in Europe. They were identical to the North American versions.

Enhanced remake:
 * On September 12, 1998, Pokémon Yellow was released in Japan. It was initially known as Pocket Monsters Pikachu, as it was based on the popular animated cartoon series. In this game, the player's character would start with Pikachu instead of being able to choose between Bulbasaur, Charmander, or Squirtle, although it is possible to obtain all three of those Pokémon within the game.
 * On October 25, 1999, North America received its version of Pokémon Yellow, named Pokémon Yellow Version: Special Pikachu Edition. It would remain much the same as the Japanese version.

2nd (Gameboy Color) Generation

 * On November 21, 1999, Pokémon Gold and Silver were released in Japan. These two games introduced a total of one hundred brand new Pokémon and the new region of Johto. These versions had limited compatibility with the previous versions.  North America received Gold and Silver on October 11, 2000.
 * Pokémon Crystal, the equivalent Yellow version of Gold and Silver, was released in Japan on December 14, 2000. It was the first version to allow players to choose if they wanted to be a male or female character, and the Japanese version of Crystal included (in a first for a handheld system) the ability to go head to head online over Japanese cell phone networks. Another notable feature that Crystal introduced is the animated sprites of the Pokemon, which are displayed at the beginning of each battle and on the status screen.  Japanese players also had the opportunity to catch Celebi, a Pokémon otherwise only available through Nintendo promotions, through these same networks.  On July 21, 2001, North America received Pokémon Crystal. However, the North American version did not include the mobile phone component.

3rd (Gameboy Advance) Generation

 * The series had its first major overhaul when Pokémon Ruby and Sapphire were released in Japan on November 21, 2002. These games featured a major graphics overhaul to accommodate the new features of the Game Boy Advance. They were also the first versions to feature two-on-two battles. Ruby and Sapphire were released in North America on March 18, 2003. The European release followed on July 25th, 2003.
 * On January 29, 2004, Pokémon FireRed and LeafGreen were released in Japan. They are remakes of the original two Pokémon games, Red and Green (Blue outside of Japan), but with many additions including the Sevii Islands. These games can trade Pokémon with Pokémon Ruby, Sapphire, and Colosseum, so new players could finally get the older monsters. FireRed and LeafGreen also come bundled with a Wireless Adapter, allowing trading and battling between these two games via a wireless connection. The North American versions were released on September 9, 2004 and in Europe on October 1, 2004.
 * Pokémon Emerald is the final game for this generation. This version is considered to be the 3rd generation's enhanced update version, similar to Pokémon Yellow in the 1st generation, or Pokémon Crystal in the 2nd generation. It has several new features, including a new battle arena (the Battle Frontier), the same wireless support that FireRed and LeafGreen has, and a new form of Deoxys. It was released in Japan on September 16, 2004, and was released in North America on May 1, 2005.
