Black 2 or White 2

If you bought Black,get White 2.

if you bought White,get Black 2.

I vote for Gandalf the grey or Radgast the brown.

I honestly lost interest in Pokemon in Gen 2, never actually playing it. That said, I'll say Black 2, because it sounds edgier. I mean, which would you rather have, a black or white Wii? 360? iPod? [other tech device]? Exactly. :)

I would be consistent, though. Did you get Black or White? Buy that new one.

either but i started playing on black so might as well go with white 2 or vice versa, try that.

There's not much of a difference (other than exclusive pokemons on different carts) plus you can get Gensect (Via interwebs) & Keldeo (via gamestop) on both carts.

Pokemon Gold.
Better than this 3DS SUPER XXXXXL TOUCH stuffs.

If you don't already have one of them, I'd suggest just getting Diamond/Pearl/Platinum or Heart Gold/Soul Silver instead.

The Black and White games aren't very good.
