As with the number of car models included in Gran Turismo 5, the game also provides an array of different tracks to race on. Some of the different categories include City, World Circuits, and Dirt and Snow. There's basically something for everyone, providing realistic differences regarding the structure and racing conditions for the different tracks. Doing some experimental driving on the different tracks will help you to determine which ones are your favorite, and which ones are ideal for certain car models.
One of the drawbacks of Gran Turismo 5 is that less than 25% of the tracks feature weather effects. This will be a disappointment for some fans of the series, since weather conditions can certainly add to the challenge of the game. For example, relatively "easy" tracks can become quite difficult to maneuver on when rain or snow exists on the track. Besides the weather effects, fewer than 25% of the tracks also include night-to-day transitions. This feature can also add to the thrill of the game, so it can be another disappointing issue for certain players of the game. The bottom line is that you should do some research to learn which tracks include the weather effects and day-to-night transitions.
Still, Gran Turismo 5 includes an array of different types of tracks, located in different cities of the world. Many players have been thrilled with the rising and falling, and twists and turns that many of the tracks have. Also, several of the tracks are replicas of actual racing tracks, which adds to the realism of Gran Turismo 5. The test track is one of the most interesting types of tracks in the game, allowing you to take a particular model for a spin before racing with it.
