This is a really bad ass looking game for the Sega Dreamcast. It is due out in the states on September 1, 2000. The game centers around kids on rollerblades 'tagging' graffiti on buildings and public transportation. The cool parts of this game are the smooth control and the style. The characters are 3D animated models rendered in flat anime style animation. The look and feel of this game are incredible. Here is what the Sega site has to say about it.

The Tokyo government is trying to silence kids, but the cops have to catch 'em first--the kids have Overdrive Magnetic-Motor Skating Shoes. And the Jet Set Radio keeps them unified and inspired to fight for their right of expression. Design your own piece of graffiti art on an immense wall in the 3D interactive city. Join like-minded hipsters who help you guard your territory from turf-grabbing adversaries. The cops are after you, too--so be quick. The 10 cartoon-style characters are pumped up with polygons so they come alive in 3D on Sega Dreamcast. Each character has exclusive abilities and style. They like to show off too--18 missions provide plenty of time to impress. It's fast, fun, funky.
