It took me about 45 hours to complete the story and then catch every Pokémon (just caught, not research level 10 for all).

I enjoyed this more then other Pokémon games since they transitioned to 3D. It's definitely the direction I've wanted them to take. That said it still needs more polish, specifically in regards to the graphics and i'd really want them to add more depth to exploration and catching Pokémon then there currently is.
