tarting out with a "knowing is half the battle" message, Need for Speed: Underground hopes to make you like street racing so much on your TV that you’ll never, ever do it in a real car. I think it may have reached that goal. The customizable cars are (as expected) crazy cool, the tracks are easy to learn but offer lots of variation, the level of difficulty is both customizable and has an excellent learning curve, and the bevy of race types will keep people enthralled for hours.
