The Wii U name has been labelled "abysmal" by Nintendo of America's former indie boss Dan Adelman, going as far as to attribute much of the console's failings to the name.

"Wii U is not selling as well as it deserves to," Adelman wrote on "It has a lot to offer with great games you can't get anywhere else. The value of the GamePad hasn't been justified. But the name Wii U is abysmal. I think that cut sales in half right there."

Adelman's departure from Nintendo was revealed earlier this week. He had been at the games maker for 9 years.

It's believed Nintendo's current failings have led investors seeking changes to be made at the top, ousting president Satoru Iwata.
