There many games that were considered to be a blast to play for the Nintendo GameCube and Pokémon Colossem was considered to be a great role playing game for that console.  The plot was interesting because it was different anything we saw in the titles we saw on Game Boy based consoles such as Pokémon Red, Blue, Yellow, Gold, Silver, etc.

Also, whoot came down to commercial sales Pokémon Colosseum was considered to be a huge success by selling over 2 million units worldwide since its release back in the early 00’s.  Generally Pokémon games are mainly on Nintendo based consoles.  If a game like Pokémon Colosseum was featured on the PS2 it would be tough to argue that it would have the same amount of success that it did for the Nintendo GameCube.
