I have a Kinect, and I recently encountered an older XBox Arcade game called Puzzle Arcade, which lists support for the "XBox Live Vision Camera". I assume this was how camera support was listed before Microsoft unveiled Kinect, but I'm unclear if the two literally mean the same thing. For my purposes I basically want to know if games which list features that require "XBox Live Vision Camera", can support those features if you have a Kinect camera.
Sadly, no. The games that support the Xbox Live Vision Camera are not natively supported by Kinect.
In fact, the two don't play nice together at all, according to this Microsoft support article. The only crossover app appears to be Video Kinect, which can be used with either device.
