Hey /vp/, so I've recently gotten back into Pokemon again starting with Soul Silver, and I'm looking forward to playing x and y as much as everyone else. In the meanwhile, I would like to play another Pokemon game to hold me over until the eventual x and y release. However, I don't want to go playing every single Pokemon game that came since the 3rd generation to avoid getting burned out on the series.

I want to pick up a game from the 5th generation and stick with that for a while until the newer one. I'm deciding between BW 1 or BW 2. Can you guys say your opinion on which you think is the better pick? I also heard one of them has a challenge mode which would make me more compelled to get the one that has that. Also what is the difference between B or W from the perspective of one or two?

Thanks for any help.
