Dear costumer,
Nintendo has removed the block on 18 plus content in the eshop, every adult can now buy these games at any time of the day from ths eShop.
A detailed research about parental controls for Nintendo systems which has been hold by a German institute for Entertainment software USK has concluded that the parental controls Nintendo offers is very good.
I am too lazy to translate the rest for you. they just warn parents to turn on parental controls for childeren.
Nice I've been waiting for this!
