Lionhead boss Peter Molyneux has said that Kinect does have some issues currently as "an input device."
Speaking to Gaming Union at E3, Molyneux - arguably Kinect's supporter in first-party terms at least - said that navigation with the motion camera was "a real problem."
"I'll admit that Kinect has got some problems. As an input device it has some real problems. Without a thumb stick, navigation is a real problem," he said.
"You haven't got any buttons, so ordering the player to do something can be somewhat of a problem."
But he did go on to say that the camera had "a great sense of freedom and emotion." So not all is gloom and doom with Pete and Kinect.
He also explained how development on Fable: The Journey - which absolutely isn't on rails at all - came about.
"It started about seven months ago when Microsoft came to us and said, 'Look we want you to do a [Kinect] experience for the core gamers'," said Molyneux.
"So we sat down and thought through the problems with that, and the first thing was figuring out how we can make Kinect more engaging, more engrossing, and more emotional than any control-based game or any Fable game has ever been before."
Fable: The Journey launches in 2012 for 360.
