Since the Nintendo Wii was first introduced, the game of tennis has always been a great example of what the innovative system is capable of doing: full motion controls. Swing the remote controller left, and your tennis racket moves left. Swing right, the racket goes right. Swing up, you lob. Swing down, you smash.
Nintendo has now introduced the Wii MotionPlus device. It's a little box that snaps into the end of the Wii Remote and allows for more precise motion controls. Again, tennis seems like a perfect fit. Now, your little virtual tennis racket can really be influenced by slight twists and turns of the wrist, or the amount of power you put behind your swing.
