Who doesn't like Road Rash? Only a lamb could not enjoy the thrill of riding motorcycles in the desert while smashing other bikers in the face with a variety of blunt objects. The game is in dire need of a sequel, and it would appear that Electronic Arts intended to give us that sequel. That is, until the game was canceled before it had even been announced.
All we know about Road Rash is that EA had someone working on something, somewhere in the world at some time. A bunch of videos showing very early test footage can be found on Youtube, but outside of that and a few examples of possible concept art, nothing else is known. All we know is that it's not happening, and that's a crime against nature.
