In the late 1980s, Brøderbund set out to make a product specifically for gamers who wanted to get a little more wrist exercise while they played. No, it wasn't a Carmen Sandiego/Leisure Suit Larry crossover (great idea, though), but rather the U-Force, a device that let you ditch the overwhelming complexity of a D-pad and two buttons for a series of infrared sensors meant to translate your adolescent, limp-wristed flailing into onscreen NES action. But give Brøderbund credit for truth-in-advertising: No one should ever. ever touch this thing.
