Once upon a time, the only way to start a car was to have your servant vigorously turn over the engine using a handcrank. Task completed, he would then walk slowly ahead of your shuddering vehicle waving a large red flag to warn other road users of your presence. That's what it feels like playing Head2Head 3D Racing. Shuddering.
If you were feeling very charitable, you'd could call it a first generation iPhone racing game; an early failed experiment from a bedroom coder. But with Asphalt 4: Elite Racing and GTS World Racing already available, choosing this would be like buying a broken Ford Model T for £1,001 when you could have a supercharged Jaguar for £1,005.
