Pokémon Colosseum is a role-playing game developed by Genius Sonority and published by Nintendo (Company). It's the first Pokémon game released for the GameCube (Platform) and is also the first Pokémon RPG designed in 3D, featuring gameplay similar to the Game Boy (Platform) Pokémon RPGs. Because of this the game is considered somewhat less of a successor to the Nintendo 64 (Platform) Pokémon Stadium series and more of a home console adaptation of the mainline games.
While similar to the Game Boy games, Colosseum features various gameplay changes including an emphasis on double battles, no Gym Leaders to fight, and no wild Pokémon to catch.
Like the Pokémon Stadium games, Colosseum also allows players to link to the handheld versions of Pokémon to battle with Pokémon from those games in full 3D.
In the region of Orre, Pokémon are being turned into heartless fighters by an evil group. You control a teenage boy, Wes, who during the opening of the game is seen destroying the evil Team Snagem's headquarters while also stealing their newest piece of technology, a portable snag machine, a device used for stealing Pokémon from their trainers. During the course of the game Wes travels around stealing Shadow Pokémon from the remaining members of Team Snagem as he discovers another growing threat in the Orre region.
Pokémon Colosseum features major gameplay changes compared to the Pokémon games of the past. In this title there are no random battles in the wild, meaning no Pokémon to catch by normal means. Instead you obtain new Pokémon by stealing them from other trainers that challenge you through the game. The catch to this though is you can only steal "Shadow Pokémon" which are Pokémon that had been stolen from their original trainers and been put through a painful process to become emotionless fighters. Thus there is a very limited number of obtainable Pokémon until you complete the main story where you are allowed to trade Pokémon over from the Gameboy Advance Pokémon games, Pokémon Ruby/Sapphire, Pokémon Emerald, and Pokémon Fire Red/Leaf Green.
Colosseum also features a more fleshed out story than previous Pokémon games with focus on clearing story points instead of going across a region collecting gym badges, as the Orre region has no gym challenge for the player to face. There is also a heavy emphasis on double battles a concept introduced in Pokémon Ruby/Sapphire, with very few one on one Pokémon battles throughout the entire game. The last major addition is with the Shadow Pokémon. These Pokémon start out only knowing one attack which causes recoil damage when used. They must be purified by spending time and fighting alongside Wes in order to gain levels, learn attacks, evolve, and be traded. Other from these changes Colosseum is similar to the other Pokémon games as you spend the majority of your time traveling from area to area while fighting other trainers to level your team of six.
