The Miiverse may well be the Wii U’s killer app, according to Nintendo North American president Reggie Fils-Aime.

A social networking application, Miiverse will allow gamers to seamlessly share achievements, comments, hand written notes, and screenshots with other users.

It will be available on Wii U at launch, and is coming to 3DS, PC, and mobile devices later.

“I think that it will pleasantly surprise people,” said Fils-Aime.

“As the network grows and the installed base grows, it will prove to be a true killer application for the system, and I say this loving what we have done with Nintendo TVii and loving all the games. Until you try it and experience it, you may not totally understand it.”

Although the Miiverse appears similar to existing social systems on competing consoles, Fils-Aime maintained that it was “a key differentiator compared to other companies in our space”.

“People have to leave the current paradigm behind to understand what we are trying to do. Miiverse is going to be embedded right on the game platform, so literally some of the activity will be able to happen immediately as people experience it,” he added.

In June it was discovered that Nintendo employees would be censoring the chat on Miiverse, which could result in delays of up to 30 minutes before a message is posted.
