Instead of all the shovelware that we are getting, why doesn't someone make a normal game where the Kinect is always running, but in the background watching and listening. If you get frustrated it can taunt you, or give you hints. If you get up to go take a break, a character can ask where you are going. If you play a stealth game and your cell phone rings, the guards can hear it and react to it. If you get distracted while playing a military shooter, your commanding officer can chew you out for not paying attention. 
 
These are ways to enhance the game instead of changing how you play it. You don't need to jump around like an idiot to have a "Kinect experience".
