I don't know if this has been discussed before, but I think doing away with Friend Codes could be done if they used age authentication combined with Parental Controls? That way a person who buys a WiiU enters their Age information, verifying they are not a minor for instance, and then set parental controls so they can only add other friends whose ages have been confirmed? That way parents can prevent their kids from associating with strangers online, and adults can just meet up with their friends without having to resort to that complicated code swapping mess? Just a thought.
