Thank you, someone more positive about it. You know, considering is a optional thing.
Your point? People under 18 can't have PSN or XBOX accounts, unless is linked to a adult parent account. Nintendo least offer opportunity for kids to have access to online features with this feature cause is a bit safer. Regardless of if we think is outdated or unnecessary or not, is their decision to do what they want.
NDS/Wii/3DS allow for playing games online with no problem be cause of friend code, and again, is aimed at kids. Not adults. Exchange friend codes, go home, play online simple, no account needed or required to setup. Maybe for US GROWN UPS is tedious and unnecessary due to is huge restrictions, but again, optional.
