Pokemon BW had one of the best stories out of the whole series. Yeah it was kind of the same "stop the bad guys" but it was a lot deeper than all the other games. If I remember correctly it had the darkest story. On top of BW2 talking about Kyurem eating people at night. Also the cut scenes were also really amazing, even when you get to meet Zekrom/Reshiram in the castle when you fought N. I also loved N's backstory too. BW was probably the best Poke Game I have played.
