It's a shame, because the basic concept isn't bad, and the presentation is reasonably good. True, the graphics don't even put Crazy Taxi to shame, let alone Burnout Paradise or GTA IV, but at least the cel-shaded visuals have a nice clean look and there are some charming small touches in the scenery.
Music is another good point, with quirky or dynamic themes for the various services and mission types. All the same, Emergency Mayhem isn't the game to make doing the right thing seem attractive. It's not even the game to make doing the right thing fun. Maybe crime doesn't pay, but it certainly plays a lot better than this.
