his previous simulators, the game nevertheless used an impressive physics engine to offer a realistic driving experience. The game enjoyed cult status among many Amiga and Atari ST gamers. Ever since the early 1990s, Crammond's primary focus has been on developing the award-winning Formula One Grand Prix series of games. The first game in the series, F1GP (aka World Circuit in the USA), was released by MicroProse on the Amiga in 1991 and is essentially the spiritual successor to Revs. Around this time Amiga Power magazine began referring to him as Sir Geoff, a running gag which has caught on with many others. The game was an instant success, earning a conversion to the Atari ST and PC platforms, but the inevitable sequel, Grand Prix 2, remained in development for three years before eventually being released on the PC in 1996. Grand Prix 3 was released on the PC in 2000 and was well received by fans and critics alike. Crammond's series now had considerable competition from other developers, particularly Psygnosis/Sony, who were licensed by the FIA to produce the official Formula One gaming titles. Grand Prix 4 was released on the PC in 2002 and is generally regarded as the most accurate game in the series. After Grand Prix 4 there were rumours that Crammond's next game would be Stunt Car Racer Pro, an updated version of his classic game. The rumours were later confirmed with an announcement that he was co-operating with Lost Toys studios. Lost Toys studios were closed in late 2003. At the beginning of 2005, the game was rumoured to be cancelled. Crammond's most recent game release is still GP4 (2002), which is still supported by fans with annual mods, in spite of MicroProse's closure in 2001. Following that, Crammond kept a low profile, but continues to engage in various programming projects.
