When I played I was very impressed and piqued my interest so much so that after several hours of play was still bored. The various tests in solo mode, may initially seem like the typical race, but the use of the fabulous "enhancers" make them a challenge. These tests will help to unlock new cars and upgrades for them. It is true that after half the game gets harder, but for me that's not so bad, it becomes more interesting and challenging to win a race. The racing style in mind, and that is through acquiring Fans anger, the more fans you have, the more rewards you get.
