Released in 1998
Like Pokémon Red and Blue, Yellow takes place in the Kanto region, which features habitats for 151 Pokémon species. The objectives remain the same as well, though some differences exist along the way. For example, in the beginning, the player is not given an option of choosing one of three starter Pokémon. Instead, a wild Pikachu that Professor Oak catches becomes the player's starter Pokémon, while the rival character takes an Eevee. The plot is loosely based on the Indigo League saga of the anime, and features characters that were not featured in the game or have been enhanced to resemble their designs used in the anime, including Jessie, James, Meowth, Nurse Joy and Officer Jenny. Similar to the anime, Pikachu refuses to evolve. Players are also given the opportunity to obtain the original three starters. As players quest on, they gradually progress catching Pokémon for the Pokédex which you use to defeat the eight Gym Leaders and eventually the Elite Four, all the while battling Team Rocket, a gang devoted to using Pokémon in order to make themselves more powerful. By the time of the encounter with the Elite Four the player has had the opportunity to capture 149 types of Pokémon; in the after game (after the Elite Four is defeated) a player may enter Cerulean Cave, where Mewtwo, the final Pokémon in regular gameplay, can be found, battled and captured. The last Pokémon in the Pokédex, Mew, cannot be captured during ordinary gameplay, though exploiting bugs in the game makes this possible.
