Peter Molyneux, creator of the Fable series and head of 22Cans, is not yet sold on SmartGlass. In an interview with IGN, he expressed concerns about its viability as anything beyond a neat concept.

He said, “Until I see some really great uses of that SmartGlass or the Wii U GamePad, the jury is out for me.” He added, “The real use for me is how it’s used as part of the entertainment experience, and then that divided attention that you’re demanding of a player is going to be really challenging to balance well.”

Molyneux is especially concerned with the idea of getting people to switch between the two screens. Describing his experience with Wii U, he said, “Getting people to move their eyes from the screen down to their laps is incredibly hard. There has to be some huge motivational thing like the words coming up, ‘Look at your GamePad now.’ If you’re going to do that, from a design perspective that sounds a bit clumsy and complex.”
