This main game, originally released in 2000, blends Music, Platforming, and Adventure genres. You navigate a stylized 3D Tokyo using magnetic roller skates to perform high-speed traversal and apply graffiti tags to claim turf against rival gangs and police forces. The core loop involves mastering movement mechanics across 18 missions, utilizing one of 10 unique characters. The game focuses on rebellious self-expression and territory control, and has since received at least one remaster.
The setting is a colorful, polygon-heavy 3D cityscape where freedom of expression, particularly through graffiti art, is under threat from the authorities. The narrative follows the exploits of the GGs gang as they broadcast the Jet Set Radio pirate radio station while engaging in turf wars across districts like Shibuya-Cho, the Benten entertainment district, and the Kogane dockyard. The atmosphere is characterized by a strong sense of rebellious energy, driven by the music and the unique visual style of the characters.
The gameplay loop centers on navigating the environment using the unique magnetic roller skates, which allow for high-speed movement and complex aerial maneuvers. A primary objective in missions involves covering designated areas with graffiti tags. Players must execute specific combinations while grinding rails or performing tricks to successfully apply their art. This requires precise control and mastery of the movement system.
The game's distinctiveness stems from its fusion of high-speed traversal mechanics with artistic expression. Beyond tagging, players engage in territory control battles against rival groups, such as the all-female Love Shockers and the cyborg Noise Tanks. Each of the 10 cartoon-style characters possesses exclusive abilities and style, encouraging replayability to explore different approaches to missions. The game features 18 core missions designed to showcase these abilities and the unique movement system.
Law enforcement, led by Captain Onishima, actively pursues the skaters, adding a persistent element of evasion to the gameplay. Successfully claiming turf often involves outmaneuvering both police forces and rival gangs seeking to dominate the same areas. The overarching plot involves the discovery of a mysterious vinyl record that rival gangs possess, which the authorities seek to control.
While initially launched on the Dreamcast, the title has received at least one remaster since its debut, making its unique gameplay accessible on newer hardware.

Jet Grind Radio (released as Jet Set Radio in Europe) is a video game for the Game Boy Advance system, which is based on the Dreamcast title of the same name. The game was developed by Vicarious Visions and published by THQ. Jet Grind Radio is an action platform game based on the Dreamcast version. The gameplay of Jet Set Radio differs in several key areas from its Dreamcast counterpart. Instead of being a 3D game using polygons, the game is a 2D game with an isometric viewpoint. The goal of the game is to traverse through neighborhoods and find key locations to tag them with graffiti under a specific time frame. Players can grind on rails and perform tricks. When a key location is reached, players must tag it with graffiti that may require a single press of a button, or a sequence of buttons that need to be pressed at the correct time. The game offers a graffiti editor to customize and create unique graffiti tags. Players can collect hidden icons scattered throughout in order to expand the number of graffiti tags. After completing the story mode of a specific neighborhood, three new time attack modes are unlocked for that neighborhood. The three modes involve tagging an entire city, racing, and performing tricks. Jet Grind Radio also offers 4-player multiplayer that allows players to compete within the unlocked time attack modes.
