Just saying, you probably already knew this, but Game Freak said themselves that they want us to play the same color version that we got last time (meaning, if you got White 1, you should get White 2). That way there won't be any continuity errors.I bought Black 2 in GameStop.
I played Pokemon White last time so I thought it would be a good idea to switch around. I particularly enjoy the benefit of Black City in Black 2 :)
