GTR: FIA GT Racing Game

Description
Armed with an official FIA license, GTR attempts to be a highly accurate simulation of FIA GT racing. The game has three play modes: Arcade for beginners, Semi-pro for experienced gamers, and Simulation for hardcore simracers. Players can choose from 70 different, officially licensed GT and NGT class cars and drive them against AI opponents or other players in online multiplayer.
In Open Practice mode, players can freely test different setups, learn the tracks, and find out how the cars handle. Race Weekend includes two practice sessions, qualifying, and the race against a number of AI drivers. Championship naturally allows the player to fight for the GT championship title through the season on authentic grids and race conditions.
In Semi-pro and Simulation modes, the cars are fully tunable to find the perfect setup for each race, track, and condition. This is necessary as not only each car behaves differently, but also track, weather, and lighting conditions change during the race. To assist the player in finding the right setups, telemetry is collected from the cars and can be fed into MoTeC's analysis software, the same one used by real GT racing teams.
