Tune, race and sometime win
First the game modes:
Grip - for me the best game mode. You get a nice sense of speed and can corner like a real car would.
Drag - has a 50% luck attached to it and on higher speeds with muscle cars it is almost impossible to cross the finish line in piece. That meant a lot of money being wasted just on fixing the car ,and the more you upgrade it the more it costs to fix it.
Drift - is my second favorite mode because it feels great when you drift thru a whole stage without hitting a wall ( with a little practice and fine tuning your car).Bottom line drifting is great!
The thing on the highway (i forgotten the name) - is in theory excellent but in practice is frustrating because one little mistake and you're out! Big bada bum and you have to use a total repair marker.
I gave the game a score 7.5 because it's not a type of game which you want to finish. It's a type of game which you play just to play it.
