If you caught the live stream of the 3DS Press Conference and ignored the trailer for Mario Kart 7 because you thought it was the same old Mario Kart you've come to love, well, there's been a change. You will now be able to choose to play in an optional first-person perspective that will be played using the gyroscope sensor.
Aesthetically, it looks really nice with the wheel and front of the kart as part of the view. But the only problem I foresee is that the 3D and the gyroscope don't work well at all with each other, as was the case with Ocarina of Time 3D and Star Fox 64 3D. Other than that, I absolutely cannot wait to see all the new things Nintendo will be bringing to this legendary series. And from what I've seen so far, the December 4th release date can't come soon enough.
