GamesRadar - As games continue to evolve, one constant keeps them anchored to the past: input devices. Controllers (and the mouse/keyboard combo in the case of PC gaming) are our firearms, our arms and legs, and our eyes. One device controls all of our senses. Now, the good thing about this is it provides a comfortable, familiar way to interact with a game. The bad? It's kind of hard to cultivate innovation outside of prettier games or a handful of new mechanics when our methods of interfacing with those games never changes.
