http://nintendo3dsblog.com/face-kart-photo...o-be-turned-off Unfortunatly, it doesn't say why. Anyone have any guesses? My thoughts are one of the following: 1 - The developers cannot get it to work as they want 2 - Maybe there's some sort of nausea effect when used with 3D when paired with a certain style of graphics? 3 - Since the game encourages motion controls, and the 3D effect is only visible when the 3DS stays still.... speaks for itself. This of course raises another question: Is the 3D effect programmed by the developers, or is the system itself the thing that produces all the 3D effect, ala Nvidia's 3d Vision on any PC game?
