Above impressions show that N'Gai Croal was not able to use Natal.
"When game consultant and former Newsweek writer N'Gai Croal gave Paradise a test drive, however, the game had trouble reading his steering actions. The footwork (gas and brakes) worked fine, but Croal couldn't steer his car at all."

Above shows a journal which reports that near-infrared spectroscopy (NIRS) is less effective on black skin as "melanin clearly interferes with the quality of the reflected NIRS signal".
As I understand, Natal uses near-infrared.
Please tell me someone on the Natal team has thought of this, or this could be the most epic failure in the history of video games.
