In the 21st century, the Tokyo city government bans kids from expressing themselves in any way. Only three things keep their spirits alive: Overdriver magnetic-motor skates, graffiti and a pirate radio broadcast called Jet Set Radio. Explore and, uh, decorate three fully interactive worlds where traffic moves at real time and pedestrians wander the streets. Watch out for police who will want to nab you for breaking the law and rival crews that want to deface your artwork. The "Cartoon Dimension" art style gives the appearance of a 2-D comic, but the characters move through it in complete 3-D. Animation runs at 30 frames per second. Ten characters are available at the outset; each has their own style and abilities.
