Gran Turismo 2 is fundamentally based on the racing game genre. The player must maneuver an automobile to compete against artificially intelligent drivers on various race tracks. The game uses two different modes: Arcade Mode and Simulation Mode (Gran Turismo Mode in PAL and Japanese versions). In the arcade mode, the player can freely choose vehicles they wish to use, and can enable damage. However, the simulation mode requires the player to earn driver's licenses, pay for vehicles, and earn trophies in order to unlock new courses. Gran Turismo 2 features nearly 650 automobiles and 27 racing tracks, including rally tracks. Compared with Gran Turismo, the gameplay, physics and graphics are very similar: the only real noticeable difference in vehicle dynamics was the brakes, which became much less likely to lock up and cause the vehicle to oversteer. The major changes are the vastly expanded number of cars, tracks and races in simulation mode. Other differences include that the player can race events separately, if he/she does not want to enter the whole tournament. The player is no longer able to "qualify" for each race entered.
