in southern europe they should do what Sony has been doing and what MS started doing for day one pre-orders

ability to buy it and pay in installments with no interest
~20€ per month

if Nintendo is the only one of the 3 not doing this, it could do serious harm in these countries. and EU is one of the regions where the second place is totally theirs for the taking..unless they screw up.

Add the one free digital game but do like in europe where they had like 10 games.
