Speaking to VentureBeat at the US Nintendo Media Summit last week, NoA boss Reggie Fils-Aime slapped down talk of Wii Music being an simple game, saying it's difficult to master and the title's E3 debut made it look too easy.
"What’s powerful in Wii Music is this juxtaposition of something that looks so simple but is wonderfully difficult to master," he said.
"We may have done that title an injustice at E3 by showing something that looked so easy. We made it appear too simple.
"Now we’re showing the tremendous variety of instruments and tones and how challenging it is to make music that sounds good."
The exec added that the game is expected to be in the company's upper bracket for sales, presumably along the lines of Wii Fit.
"We don’t publicly talk about sales targets but our expectation is it will be one of our top sellers," he said.
Lots more through there.
