The Miiverse, Nintendo's bespoke Wii U social network and operating system hybrid, won't support Facebook or Twitter, the platform holder has confirmed.
Speaking to GI International Nintendo of Europe's Laurent Fischer said social interactions will be limited to fellow Wii U users, but detailed plans to extend the Miiverse to mobile platforms and browsers.
"What we have discussed so far... I think it is the other way around, from any devices in the future you will be able to access the Miiverse, from mobile phone or laptop," said Fischer. "You can check what's going on and even participate."
Unlike competing platforms Nintendo isn't interested in providing services that can be readily accessed on numerous other devices.
"I have three devices permanently doing that already, what is our benefit to do so also?" he said.
Instead the platform holder intends on providing the Wii U community user-friendly ways for players to interact.
"On the Wii U we do have additional reasons for connecting, we talked about things like the video chat system, nothing revolutionary but it's going to be convenient, it's going to be easy.
"And the Miiverse is the one actually that I believe has a very unique feature which is we put ourselves in the situation of making sure the people you can communicate with they are somehow already in a kind of community. The community will be the Wii U owners, who will have this common interest for video games and our expectation about that is it's going to be a way to enhance the idea of sharing information on the video game."
Nintendo has said it plans to moderate Miiverse interactions, which means user messages could be delayed by 30 minutes.
