Pokémon: FireRed and Pokémon: LeafGreen return longtime trainers to the land of Kanto, which was featured in the original Pokémon: Red and Pokémon: Blue. Here, they'll collect new pocket monsters, uncover new secrets, and put a stop to another of Team Rocket's greedy schemes. Like earlier Game Boy editions, this autumn 2004 episode in the life-sim role-playing series is available in two slightly different versions. Both FireRed and LeafGreen take place in the same game world and follow the same storyline, but certain Pokémon are found more or less frequently in either version.
Gameplay involves exploring the various regions of Kanto and engaging in Pokémon battles with other characters, who may offer information, items, or advancement when defeated. Players can also hunt through the countryside, in hopes of finding and capturing rare wild Pokémon that may live there. Pokémon collected in FireRed or LeafGreen can be traded among the immediately previous Ruby and Sapphire versions of the game, and with the GameCube's Pokémon Colosseum.
Of special note is a piece of hardware that comes bundled with all original retail copies of Pokémon: FireRed and LeafGreen: the Game Boy Advance Wireless Adapter. In games that support the accessory, it allows chat functions and other link cable-type connectivity, without any of the cables. If players visit certain community areas in the Pokémon: FireRed or LeafGreen, for example, they'll be able to meet and send wireless messages to other players who are sitting nearby. As many as 40 Pokémon players can share these virtual environments at the same time, and chat rooms can accommodate as many as five "buddy" players at once.
