A two player, two DRC battle simulation. Each person holds a Remote in their dominant hand and the DRC in their off hand. A special strap or attachment allows you to hold it so that its screen is facing your opponent. The Remote is your laser gun, the DRC is an "force-shield". You try to shoot at your opponent while trying to keep your DRC poised in a way that it blocks your opponent's shot. On the TV, a really nicely rendered third-person approximation of what's going on is shown from various, sweeping angles with amazing camera and art direction. The controller screens provide a very basic hint showing how weakened your opponent is. Whether or not you hit your opponent depends on how close their DRC's sensor strip is (especially vertically) to where you were pointing the remote.
This one is a clever idea that won't really go anywhere but could be fun for some. It's rare in a video game that you actually face your opponent, so this would feel more like a realistic confrontation.
Yeah, there are some possible applications of this kind thanks to the Wii U setup, think of a giant augmented reality pong, where each player control his own bar while moving in the living room with its padlet.
But it's only if at least 2 DRC will be supported.
