It seems that Nex Playground tracks the player similarly to the original Kinect, minus the 3d space mapping, so many of those games would be a natural fit. Back in the old Xbox Fitness days, they had awesome Kinect apps for Mossa Fitness and even Beachbody Insanity. This would be an amazing fit for the Nex Playground. Nike also had a Kinect-based Xbox fitness game separately that would be awesome. Oh, and more events for the family fitness challenge would be epic! Something SIMILAR to the original Kinect Sports seasons one and two would be amazing as well.
