The Warrior Wave game, which is the one that you installed, is for the F200 and RS-300 'desktop' cameras, whilst you are using the R200 'mobile' camera. They are not the same hardware. So the camera is likely working with no problem.
I'm afraid I could not find an alternative R200 program to test your camera with. Available applications seem to be mostly for the F200 and SR-300, as the R200 was designed for outdoor image processing rather than playing games with the hands and face like the desktop cams. I recommend trying one of the sample applications for the R200 in the Sample Browser application that comes packaged with the SDK. Usually the browser is installed to our desktop in a folder called 'Intel RealSense SDK Gold'. Good luck!
