This is why there should be a sequel. Or at the least, an expansion. The storyline was too short. When I bought the game, I thought that you had to defeat all of the legendaries to beat the game, but you only had to beat a handful.
So that was a letdown. Then there wasn't much to do after the credits. <3 Though I did enjoy the Gengar mission. Anything to see my bishie again. *glomps Gengar*
