Xbox 360 Kinect: It Doesn't Play Standard Xbox Games, Only Kinect-Enabled Titles

No. The Xbox 360 Kinect is a motion-sensing camera peripheral, not a console. It cannot play standard Xbox 360 games (disc or digital) on its own.

Function

• Connects to Xbox 360 (USB + proprietary power for launch model).
• Enables controller-free interaction via body tracking, voice recognition, facial recognition.
• Only works with Kinect-enabled games (Kinect Sports, Dance Central, Kinect Adventures, Fruit Ninja Kinect, Child of Eden).
• Some standard games added optional Kinect features (voice commands in Mass Effect 3, Skyrim, Madden; head tracking in Forza 4).

You still need an Xbox 360 console + controller for the vast majority of games.
