Nintendo has informed Wii U and 3DS users that it has lifted the access restriction to content rated 18+.

Previously users could only access and buy 18+ rated content between 11pm and 3am.

"Nintendo has lifted the access restriction to content rated 18+. Adults can now browse and buy all games at any time of the day," explained the Nintendo eShop Team in a letter posted on NeoGAF.

"Following analysis of the Parental Controls system on Wii U and Nintendo 3DS in cooperation with USK, the German Entertainment Software Self-Regulation Body, it was deemed that Nintendo's Parental Control system is of very high quality and offers a remarkable level of protection for children. Nintendo's Parental Control system was found to have proved itself in practice.

"Nintendo always encourages parents to make use of Parental Controls to control access to content they deem inappropriate for their children."

The restriction seemed somewhat silly, so it's good to see it lifted and the responsibility put onto parents.
