The Playstation Vita is an impressive piece of hardware but it needs better games, says Nintendo’s Shigeru Miyamoto.

"It's obviously a very hi-spec machine, and you can do lots of things with it. But I don't really see the combination of software and hardware that really makes a very strong product," the Nintendo legend said during an interview with Edge magazine.

Drawing parallels between the Vita and his own company’s 3DS launch, Miyamoto went on to suggest that all was not lost for Sony’s portable device.

"When we launched the 3DS hardware we didn't have Super Mario 3D Land, we didn't have Mario Kart 7, we didn't have Kid Icarus: Uprising," he said. "We were striving to have all of these ready for the launch, but we weren't able to deliver them at that time.

"We were kind of hoping that people would, nevertheless, buy into the product, find 3DS hardware promising, but looking back we have to say we realise the key software was missing when we launched the hardware."

Vita sales have plummeted following a strong launch, even in Japan where Sony has traditionally dominated the handheld market. It is even being outsold by its predecessor, the PSP.

Conversely, the 3DS has topped hardware sales charts in Japan every week since August 2011.
