The Legend of Zelda: Skyward Sword introduces full motion control enabled by the Wii MotionPlus accessory, which synchronizes your movements with Link's actions while offering intuitive play control. 

With the Wii MotionPlus accessory, every movement of Link's sword matches your motion with exact precision. If you motion left to right, Link swings from left to right. The precision play control is applied to enemies as well, as you must contemplate strategy when battling opponents that actively try to defend against attacks.
