is B2/W2 a remake of B1/W1 ? or is it an expansion to it? i haven't played either one of them yet so i'm not sure.
I don't own a DS or a 3DS, will the DS Pokemon games work on the 3DS? or just the DS only?
and, I know the DS/3DS has internet/wi-fi on it, is it worldwide so i can battle/trade with anyone around the world? or is their a certain range on it? I think i got all my questions right here, well let me know, thx
Black 2/White 2 are sequels to the original Black/White games.
Black 2/White 2 work fine on any DS.
Not sure about the third one, though.
