JGR: Amazon.com Review
In Jet Grind Radio, you play a whacked out kid who's completely torqued off about the system. It seems that the city of Tokyoto is not terribly kid-friendly and wants to keep things neat and pretty. You, the skater punk, figure that the only way to rebel is with your inline skates and a couple of cans of Krylon. That kind of attitude can lead to trouble when you're in the real world; but, in the world of Jet Grind Radio, there are no paint fumes, and it's all done in the name of fun and scoring points.

JSR:Amazon.com Product Description
You say you want a revolution? The setting is Tokyo, the year 2024. Freedom is a valuable commodity, and freedom of expression even more so. The thumping beats and mean streets of the original freeform counterculture skating game Jet Grind Radio are back in Jet Set Radio Future. Featuring unique comic-style graphics, new tricks, and hot tunes, Jet Set Radio Future brings the hip skate game into a brave new world. Choose a character, strap on your rocket-powered skates, and immerse yourself in living, breathing cities filled with opportunity. Along the way, you'll compete with rival gangs, be chased by cops, and perhaps discover something unthinkable. Join up with a friend and work together to reach new places, create new attacks, and perform astounding stunts. Wherever your adventure takes you, it's all about extreme skating, extreme action, and, of course, extreme style.
