Richard Marks has an impressive resume: He has created the EyeToy, the PlayStation Eye and the PlayStation Move. He also likes buttons.

"Buttons are irreplaceable as an input device," Marks tells Edge Magazine. "Too many buttons are overwhelming, but one single action button is very powerful feeling."

Continuing, Marks adds, "For core games you really do need a set of buttons to quickly choose things. Trying to replace buttons with gestures doesn't work very well."

This fall, the PlayStation Move is going head-to-head with Microsoft's Kinect. The Move has buttons. The Kinect does not.
