Mark Rein says none of the second screen functions available now on Wii U and SmartGlass add real value to a game.

Speaking with Alist Daily, the Epic Games vice president said, “I think we’ve yet to see the real value of the second screen idea, if you’re talking about [Xbox] SmartGlass and companion apps and things like that. But that doesn’t mean that it won’t be big one day. I don’t really know what it is yet.”

“Where it fits into gaming, I don’t know,” he added. “I’m not sold on picking up my tablet to choose my play and then putting it back down and picking up my controller. It’s kind of a wonky way to choose to play, so I don’t know if that’s how it’s going to go or not.

“Developers should try everything and have lots of fun with it, and sooner or later there will be a killer app for that sort of thing, too.”

Few high profile games currently include second screen functionality. Battlefield 4’s Commander Mode can be accessed on tablets. Ubisoft's Watch Dogs and The Division will both include second screen functionality.
