Chaos GP

Chaos GP is the main 1-player game mode in Sonic Drift and Sonic Drift 2. In this mode, the player competes against three other computer-controlled racers in a series of six races on six different courses.

Description
The Ghaos GP is a gameplay mode where the player choses a playable character to race against three other computer-controlled competitors, which are three of the other playable characters in the games, in a series of six races.

Each game has three separate circuits for the Chaos GP (named after a color) with each featuring six different courses that they player is taken through. No racing track on the courses in the circuits is the same, even when the course in question is reused in another circuit; instead, the courses may hold alternate racing track for each circuit. At the end of each race in a Chaos GP, each racer, the player included, is awarded with an amount of points based on his/hers finishing position in the previous race:


 * 1st Place: 3 points
 * 2nd Place: 2 points
 * 3rd Place: 1 points
 * 4th Place: 0 points

After the six races in the chosen circuit has been completed, the racer who has amassed the most points wins the Chaos GP. If there is a tie for total points, the racer with the most 1st-place finishes wins. When winning the Chaos GP, the player is awarded with a Chaos Emerald.

The Ghaos GP is the main gameplay mode for the single-player in Sonic Drift and Sonic Drift 2, where the objective is to win each of the circuits available in the Chaos GP in order to complete the game.
