Forza Horizon is an open-road game based around the fictitious Horizon Festival, a street racing event set in the state of Colorado. The game incorporates many different gameplay aspects from previous Forza Motorsport titles, like the large variety of cars, specifically around 300 cars, realistic physics and high definition graphics. The aim is to progress through the game by means of obtaining wristbands via winning races, while also increasing their popularity level by driving fast, destroying property, and performing other stunts and antics. Horizon features the physics of Forza Motorsport 4, which have been optimised to work on the 65 variants of terrain said to be present in the game. Players can drive off-road in select areas, while others are limited by guardrails or other means.
