Jet Set Radio is a 2000 action game developed by Smilebit and published by Sega for the Dreamcast. The player controls a member of a youth gang, the GGs, as they use inline skates to traverse Tokyo, spraying graffiti and evading authorities.

Player controls a member of a gang of graffiti-tagging Magnetically Driven Inline skating inline skaters. The game consists of three types of levels: Street, Rival Showdown, and Trial. The Street levels come in two categories. The first is to tag every graffiti point in each area previously tagged by a rival gang before the timer runs out while evading the authorities. The second category serves as a boss battle by chasing the rival gang members and spraying graffiti on them. The more graffiti points are sprayed, the more deadly the authorities become. Graffiti points are marked by arrows and require paint to tag them. Players can spray graffiti by either pressing a single button or inputting commands using the analog stick depending on the size of the graffiti spot. Players are unable if they run out of paint and must be refilled by obtaining yellow and blue spray cans scattered across the stage. Yellow spray cans refill a single spray can and blue spray cans refill five. Enemies will pursue players and attempt to deplete their health. Health can be replenished by obtaining red and green spray cans. Performing tricks add bonus points to the player's overall score and gain access to areas difficult to reach.
