Check out RB3 and Apache: Air Assault too.
Kinect Joy Ride heads up a fresh batch of demos available on Xbox Live today.
You can also sample Harmonix’s Rock Band 3 and Activision’s chopper sim Apache: Air Assault.
You shouldn’t need a demo to convince you to open your wallet for Rock Band 3. Johnny Minkley’s perfect 10/10 review should be all the impetus you need.
