Utterly Awesome
The World Player mode is just awesome, so many different races you can participate in, with my favourite the Traffic Attack, where you are allowed to hit traffic to score money.
Burning a Lap was fun, but you really needed to know all the shortcuts to win the gold, but in the Formula One cars you could win with no troubl.
Road Rage allowed you to receive a massive rush when hitting a car off the track and getting a reward for it and the even bigger rush would be from taking down a rival who hits you previously, with your mind going mad into Revenge and your ego wanting to take them out so bad.
Eliminator was hard, but the main thing you needed to do was get first early in the race, if you were 4th when the last place car was eliminiated it would be hard for you to stay in the fac. If you were first for the whole thing, the only thing you needed to do stay their!
Crash Events, the biggesr rush in the game, hitting many cars for a Medal. The harder levels provided good crash events making you work harder to get a medal.
Grand Prix, was enjoyable allowing you to connect all your fun of the previous races into an even, where you must remember all the shortcuts and stay cool to win the whole event.
Preview put you in the best cars, usually Formula One cars.
