Though second screen capability is starting to come into its own for the Xbox One and PS4, having been introduced with the Wii U, Epic Games vice-president Mark Rein still feels that we’re yet its true value, though it could be big one day.

In conversation with the [a] List Daily, Rein stated that, “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. 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.”

As of now, functions of second screen apps include being able to spectate on some one’s game, accessing certain in-game functions (calling an air-strike in Dead Rising 3, for example) and small mini-games within the main game.

Revamped in tme for the launch of the PlayStation 4 in Europe, the PlayStation App adds a multitude of functionality for those with smartphones and tablets. You can use the app to access PSN and view your profile, view the PlayStation Store, check what your friends are up to and what’s currently new, view footage and spectate on friends’ games and much more. It also adds second screen functionality with some games and lets you control your console using your smartphone.

The PlayStation 4 is launching in Europe on November 29th, which will round out the release of next-gen consoles across all Western countries. Thus far, it’s been commercially successful, despite criticisms of a weak launch line-up and some units affected by hardware issues.
