Grand Prix Circuit is a Formula 1 racing sim created by Distinctive Software for PC and Commodore 64 in 1988.
Later it was ported to Amiga, Amstrad CPC, and other platforms. The Amiga version has more colors than the 16-colors MS-DOS version and uses the fantastic music composed by Kris Hatlelid for the C64 edition. In the game, you can drive the McLaren-Honda turbo of 1988 (the legendary car of Ayrton Senna and Alain Prost), the 1989's Williams-Renault, or the Ferrari 3.5 liter V12.
Grand Prix Circuit had the ambition to be a simulation, so the car's behavior is quite realistic. You have to be careful while driving because the vehicle is very sensible. At the same time, there are not many options, and the pit stop is quite simple too. So the learning curve is not too hard. You can grab your joystick, practice a bit, and be ready to race soon.
Considering that the game was developed in 1988 and was made for 8-bit platforms, it was pretty remarkable. True, three years later, Geoff Crammond would release a masterpiece called Formula 1 Grand Prix, but the title by Distinctive Software, with the right mix of simulation and arcade, still maintains its charm today.
