According to ESRB, this game contains: Animated Violence, Mild Language
Parents can feel good about purchasing this title for the 10-year-old and above, though it does put the player in role of vandals who make a living out of avoiding the police. There's also a heavy gang environment present, and some mature language used by a few characters and in some of the song lyrics. Sega rightfully placed a disclaimer at the beginning of the game discouraging the use of graffiti as vandalism. Jet Grind Radio is the U.S. release of the original Japanese game, Jet Set Radio, which cleverly took its name from the pirate radio station in the game. Sega was forced to change the title for American localization due to copyright reasons, choosing the name "Grind" after one of the cities in the game, Grind City.
Sega fans have another instantly recognizable hit on their hands with Jet Grind Radio. It's one of those games you can show off to any friends who have a PlayStation 2.
More ordinary videogamers might appreciate Jet Grind Radio's arcade approach and fast action—which makes the game easy to get into and easy to put down—but its intense difficulty is more suited to rabid gamers.
