Microsoft's demo of Natal was one of the most talked about moments from E3 2009. The first question was: Does it work? Yes, it does indeed work. Microsoft's demonstration of Natal focused on games created specifically for the new motion-sensor camera. But what has IGN excited for Natal are the ways it can enhance games that use the normal controller. Natal can recognize facial expressions and even subtle hand movements.
With that in mind, IGN has five games already available in stores that could be enhanced by Natal. Obviously, these games can't actually use Natal currently, but this is just an example of how the new motion camera can be used to enhance games without turning them into gimmicks.
