Really Quick Updates: One per system, not per game.
Nintendo of America President and CEO Reggie Fils-Aime has taken to the stage in New York City to announce that Nintendo 3DS will use a friends code like its bigger brother, Nintendo Wii. However, unlike the Wii, the 3DS friend code will be singular. It won't be software dependent. So, when you exchange your Wii friend code with a real-life friend, then there's never a need to do it again. It's not quiet a gamertag, but it's close.
