Cuz White sucked for me. It was too easy, I much prefer my Pokemon Leafgreen.. sadly.. PKMN LG was one of the games that were stolen, I got a new one.. but I had a shiny D:
I just hope they improve, I also dislike both Character designs, but that isn't a big deal.
BW2 will have an easy and hard mode. B2 gets hard mode and W2 gets easy mode. Though you don't unlock it until post game. It's suppose to be a way to raise or lower the challenge for your friends who haven't beaten the game.
