Wii Sports was the technological demo that came packaged with the Wii. The system was a Renaissance in a stale gaming world where Nintendo, again, proved themselves to be the masters of innovation. The motion controls were fun even for punks who thought gaming was dork exclusive. But the problem was Nintendo didn't expound upon them much afterward, we were amazed to see no new attempts at an established Mario Sports franchise (like Tennis or Golf) that truly capitalized on the hardware's specs. 

Eventually someone will perfect this concept and run with it. We envision a world where people play an entire baseball season with a bat controller or an entire football season where you wear a helmet that authentically simulates brain trauma.
