Think Crazy Taxi. Now replace the characters with characters from the ever popular TV show The Simpsons and turn the city into a giant 3D repesentation of Springfield. That's basically what Simpsons Road Rage is.The evil Mr. Burns has bought the public transport system and turned the busses into nuclear powered death traps. So the citizens of Springfield try to earn the money to buy the transport system back by becoming...well crazy taxi drivers.
