Before each race, you can run some practice laps to get a feel for the track (there are more than 15 in all). After you feel comfortable, you can go for the time trials, and how well you did will determine your placement in the race. Every race earns you points (the better you do, the more points you get), and these points determine who is king of NASCAR. Besides the aforementioned lack of speed, I also had a few problems with the computer A.I. The other drivers are like T-1000 cyborgs -- you can try to cut them off or crash into them, although they often will brake to avoid you -- even when you are coming up from behind to “tap” them (perhaps into a spin), they almost always see you coming and break, swerve, and avoid you like a hot chick at a Babylon 5 convention.
NASCAR 99 was a little too unrealistic for me.
So why did I give it an 85%, you ask? 75 plus 10 bonus points for being able to play as someone named "Dick Trickle".
