The worlds for open world 3D driving sim yadda yadda. What I loved about this game, besides the metal soundtrack and pure fun of choosing whether to race, or simply plow all your opponents into oblivion, was how much detail they put into the engine. Use the IWANTTOFIDDLE cheat and check out the DATA/CARS files. You'll see all sorts of options for changing anything from center of gravity to compression, rebound, spring rate, ride height, allowing you to tune any car from rock crawler to drift racer. Talk about replay value!
