thinking about upgrading to NN3DS for the C-Stick in Moon Chronicles and Nano Assault, if not for those eShop exclusives i would go all physical cartridges. but i cannot system transfer if they require a NNID. the reason is NNID locks your region. Canada eShop doesn't get all the games. haven't cross checked, but at least one game is MIA: Kokuga. do you have to have NNID to system transfer?
