Travel back to the Orre region, 5 years after the events of Pokemon Collosseum...and basically play a ten times better adventure, with new plot twists, and better Pokemon to catch and train. This game actually gives you a little more freedom than it's predeccessor, because it's starter Pokemon, which is Eevee, hasn't already been evolved and you can select any of the five evolutions you want, Jolteon, Vaporeon, Flareon, Espeon, or Umbreon. It's your choice, and you can have the evolve shortly after the beginning of the game. It's not as hard as Collosseum, and it's more fun that it as well. Just prepare for as much fun as you can possibly handle, because you're going to get a lot of it.
