There won't be a pervasive "achievement" system on Wii U, Nintendo of America president Reggie Fils-Aime suggested to Kotaku. Referring to the 3DS's system-specific achievements, which honor StreetPass-based activities in the system software, "We will have that," Fils-Aime said. "Once you start getting into game-specific [Achievements] that's developer driven."
Fils-Aime hinted at changes to the friend code system for connecting to online friends, calling the new system "friend codes, but it's not the existing friend code system." He added, "you will be able to identify people as friends and have a certain level of interaction versus a different level of interaction for the more general population. The method by which you identify someone as a friend is a lot simpler than what's happening today with Friend Codes." However, he didn't go into detail.
Fils-Aime also had good news regarding the announced content filtering system. It turns out that messages that aren't flagged by an automatic scan won't be subject to manual scanning. If a message is flagged by that, and then by the community, then Nintendo steps in.
