Almost, we choose a game then get a code to download that game, so the choice comes before the code.

I see, thanks.

Still, this limits the number of people with codes to trade as most buyers will choose a game they don't have and want :-/.

It would have to be coordinated with someone willing to wait a bit but the potential trades could happen between someone from Europe wanting to download Pikmin 3 and someone from NA wanting a game outside the 4 we have available.

I do realize there's nothing to gain for the people in Europe except the gratitude of a fellow NA VGC user.
