Graffiti is art. However, graffiti as an act of vandalism is a crime.
Jet Set Radio is very nearly a complete metaphor for freedom. Smilebit accomplished the task by making its game small in scope and using every element of its design to construct a theme: it has a large, overbearing enemy in its fascist Tokyo-to and a graffiti mechanic that is an action-oriented, easily understood core concept that is itself a means to fight against the oppression. It gives characters the tools to move deftly through and around the world to leave their mark. With the guidance of free-wheelin’ DJ Professor K and his pirate broadcast, the youth are rebelling in the heart of Tokyo-to and the pressure is boiling up from the underground.
