Well that depends, really. If we're talking about the idea as the "big idea" per se, then brace yourselves, because it was in the minds of the game pioneers at Nintendo long before the electronics giant thought of making a second Second Life without the persistent game world.

In fact, it was conjured up by legend Shigeru Miyamoto two decades ago, but it was never realized as a full game. Last week at the Game Developers Conference, a Nintendo spokesperson claimed that the PlayStation Home "is an example of Sony's Mii-too approach."

A report from Jolt quoted Miyamoto stating, "We've been working on this idea of twenty years and never been able to turn it into much of anything. The view was it would be very popular with creative artists. But the view [also revealed that] it was too complicated and would make most players frustrated."

The Redmond folks were also speculating that some features from Microsoft's Xbox Live were "definitely taken," although they applied little pressure against Sony and gave them a pat on the back instead. "I think they've definitely taken some concepts that we originated like achievements, but I think they're pushing in a different direction and we've sort of fundamentally got two different approaches going on here," said the Microsoft spokesman.

They believe that the PlayStation Home is gearing towards becoming a whole different "little game" in the long run, and they'd rather center a community around the games for their console than create a community with a game. "Our approach is the other way around; it's that games are the center and that's the star of the show... that's what people buy the console for," he concluded.

But if we're talking about the actual game itself, then Sony gets to bring home the apple pie.
