In an effort to appeal to the self-improving side of gamers, GameStop is launching a  “Play Your Way” sweepstakes, offering four luxury Caribbean vacations, linked to the purchase of such fitness-inspired titles as Kinect Sports Season 2,

Just Dance 3, The Black Eyed Peas Experience and

Zumba Fitness: Join the Party. As an added incentive, the Grapevine, Tex.-based retailer is offering a free FitBit Ultra Wireless Activity Tracker (a $10 value) via mail, with the purchase of an Xbox 360 Console with Kinect and a qualifying Xbox 360 game, while supplies last.
