The storyline is exactly the same. you start training for some old fart in a labcoat, you go for badges, some bad team tries to use pokemon to take over the world while your at it, you kick them in the butt, get a cool legendary out of it, you go fight the E4 and the champion is someone you've seen before, game ends. Pokemon has never had much of a real story. It's always been about training, battling, collecting, and testing it against other people.What makes DP such an awesome game is the fact that you can bring all of the pokemon together into one game, fairly easily. and by fairly easily, I mean by importing them from other games. if you can actually find someone willing to trade you for pokemon like mewtwo, Rayquaza, and such locally, since oyu can't trade over the trade station for pokemon you haven't seen, then I admire your patience. but the rest of us, we like just bringing our pokemon over from our other games, thank you.
