Road Rash is a motorcycle racing video game series by Electronic Arts in which the player participates in violent, illegal street races. The series started on the Sega Genesis/Mega Drive and was released on various other systems over the years. The game's title is based on the slang term for the severe friction burns that can occur in a motorcycle fall where skin comes into contact with the ground at high speed. Six different games were released from 1991 to 2000, and an alternate version of one game was developed for the Game Boy Advance. The Sega Genesis trilogy was re-released in EA Replay for the PlayStation Portable. The series sold 3 million units by 1998.
