"According to data provided by the NPD Group, the top-selling Move-required title in January 2011 was The Fight: Lights Out, a game in which the Move controls are used for fist fighting. With Fight sales of only 16,000 units for the month, we can conclude that all other Move-required titles had similarly low sales. That list includes titles like Sony's EyePet, SingStar Dance, Start the Party!, Kung Fu Rider, The Shoot, TV Superstars, and Ubisoft's Racquet Sports."
