Pokémon was originally released in [[Japan]] in 1996 as a pair of cartridges, ''Pokémon Red'' and ''Pokémon Green'', for the original [[Game Boy]] system. Three years later, the games were released as ''Pokémon Red'' and ''Pokémon Blue'' in the United States and worldwide. The games feature similar gameplay, differing primarily in what monsters are available in each version. New versions of the game are released periodically, normally in pairs, to introduce new monsters and to take advantage of improving hardware technology. As of the release of ''Pokémon Platinum'' in 2009, there are over 490 Pokémon species available. | Pokémon was originally released in [[Japan]] in 1996 as a pair of cartridges, ''Pokémon Red'' and ''Pokémon Green'', for the original [[Game Boy]] system.
