Jet Set Radio

Jet Set Radio (originally released in North America as Jet Grind Radio) is a 2000 action-platform video game developed by Smilebit and published by Sega for the Dreamcast. The player controls a member of the GG's, a youth gang that uses inline skates to traverse Tokyo while spraying graffiti, challenging rival gangs, and evading authorities.

Development was headed by director Masayoshi Kikuchi, with art by Ryuta Ueda. The team drew influence from late 1990s Japanese pop culture, such as the rhythm game PaRappa the Rapper, the anti-establishment themes of the 1999 film Fight Club, and elements of 1980s American hip hop culture such as graffiti. The environments were based on Tokyo shopping districts in Shibuya and Shinjuku, with graffiti designed by artists including Eric Haze, who also designed the game's logo. Jet Set Radio was the first game to use a cel-shaded art style, which was developed in response to the team's disappointment with the abundance of sci-fi and fantasy Sega games.

Upon its release, Jet Set Radio received universal acclaim for its graphics, soundtrack, and gameplay. The game won several awards while being nominated for many others, and is considered one of the greatest video games of the 2000s and of all time. In 2003, it was followed by a Game Boy Advance version developed by Vicarious Visions, as well as versions for Japanese mobile phones. In 2012, it was re-released for the Xbox 360, PlayStation 3, iOS, Windows, PlayStation Vita and Android. The game also launched a series of sequels, starting with Jet Set Radio Future for the Xbox in 2002, and another being announced by Sega in 2023.
