I never said that content wasn't locked to nnid.I know what i'm talking about & its not club nintendo if the games aren't tied to Nintendo Network then explain this on my WiiU I have 2 accounts & forgot the password to one of them I decided to delete it because there was no way to get a password reset due to the email having a slight error when I was about to hit delete account & I qoute it said " If I deleted the account I will lose all content asociated with the account so I didn't delete the account. I've said it before i'll say it again any & all content on a system wether it be a 2/3/DS or WiiU its connected to your Nintendo Network account not the system.
I said that nnid is locked to the SYSTEM.
The point being that you can't use the same nnid on 2 separate 3ds. Which is exactly what ninty says on their website. If you don't like it then go take it up with ninty.
