"Asymmetric gaming" as described here:
providing players different control schemes and specialized objectives in the same game scenario. This is a departure from traditional console game mechanics. Most current games involve a discrete set of roles and strategies, and these are enabled and governed by a single (symmetrical) set of controllers. By introducing a new kind of controller and screen into this mix, Wii U opens up the possibilities for new roles and perspectives, and therefore new kinds of gameplay – asymmetric in nature
Why do I blog this? Writing a chapter about the evolution of game controllers, and the resurgence of displays, this notion is interesting to be addressed in conjunction with technical means and players’ reactions.
