Nintendo have ventured into a more open online experience with Wii U, but you'll need a credit card to register if under 18.
Parental controls can make the interaction with Miiverse a lot safer for the young ones, but according to new system adopters in the US, if players pop in a date that's under 18 years old, a credit card will be needed to verify.
Anyone could of course lie and claim that they've suddenly shot up into adulthood, however those who have the Triforce of honesty will need to charge a valid credit card with $0.50 cents.
There are warnings every step of the way, so if a rouge phallic drawing sneaks up into the Nintendo Network, tough noogies.
