The 'Championship' mode is by far the most creative measure of game progress I have seen to date. In this mode, you, playing either Jarrett or Labonte, must decide between race team offers. Teams will offer you to drive for them, for a particular tournament, and set out minimum criteria for completing the task. Most of these offers require that you complete a time trial on a particular track, driving that team's car. This setup has a wonderfully addictive quality, and also manages to motivate in a way that most games cannot.
Progression quickly becomes obsession.
The cars are difficult to handle, but not impossible. The races are incredibly competitive and mistakes are punished immediately. The cars are all susceptible to realistic damage. From minor fender damage to full-on engine and suspension damage, the damage meter is a significant factor to keep in mind while racing. Many races feature a mandatory pit stop, an obvious feature missing in virtually all other racing games.
