I go only to register my games. But that is an adventure because 9/10 times I have to go through a whole bunch of crap just to sign in. It tells me something is wrong and I have to sign in again, and it would be no problem, but for some reason I have a very strange user name of letters and numbers that do not form words, but nonsense. Also I can go to the website and it says I am still logged in, but when I try and register it says something is wrong and I have to sign out and then back in again and go through hell adventure again possibly just to register and get NOTHING out of it.
Seriously I don't even see the reason for MY NINTENDO when it's useless, where is the incentive to buy games and register them, when Nintendo doesn't give anything good. In Europe they give points you can use for neat things and I guess Japan has a similar deal, but we get nothing. Maybe once in a blue moon something like a PINK STYLUS if you bought Kirby Canvas Curse or something, but that is so far and between that it's a joke.
I want a true incentive program Nintendo. Give me a reason to register my games, not a possible chance for something in the furture, but something now.
