No telling how really real this is because it’s just a teaser video, but we have what appears to be a Mario Kart-like game for the iPhone. It’s apparently being developed by France’s int13, but I found no mention of the game itself on the company’s site. The steering wheel looks interesting and the little cursor appears to perhaps control your kart’s acceleration depending upon whether it’s positioned higher or lower on the wheel.
