The guy who designed one of last year's biggest blockbusters hits the hay each night dreaming about the ultimate game. He just can't make it happen yet. "It's a world that can flip upside down in a second and change from an empowering fantasy to a dreadful nightmare," Cliff Bleszinski, lead designer of Epic's Gears of War, says of his dream game. "It all hinges on thoughts and impulses-not on button presses. The biggest obstacle we're facing now is one of interface. We need a significant advance in this area for gaming to truly allow for an interactive landscape of dreams."
