Turbo Esprit
Turbo Esprit is a video game published by Durell Software in 1986 for the ZX Spectrum, Commodore 64, and Amstrad CPC. The game was very detailed and advanced for its time, featuring car indicator lights, pedestrians, traffic lights, and a view of the car's interior controls. It may also feature the earliest example of a free-roaming city environment in a computer game. "Turbo Esprit" was the first free-roaming driving game, and has been cited as a major influence on the later "Grand Theft Auto" series.
