To add to the abundance of off-screen, portable demos that are being uploaded, here’s yet another. This one comes as a result of the unsurprising announcement that the Mario Kart franchise would be coming to the 3DS. I still have to say that the car customization available before each race is the game’s coolest feature. The game is currently on show at E3, and we now have over 6 minutes of gameplay which you can watch below. Be warned however, the person playing is not very good. At all.
