In the mid 1980s, Codemasters and the Oliver Twins released a number of games with "Simulator" in the title, including "BMX Simulator" (1986), "Grand Prix Simulator" (1986), and "Pro Boxing Simulator" (1988). Richard and David Darling of Code masters were inspired by Concertmaster's best-selling games, which were based on real sports such as football and BMX racing, which had a pre-existing popularity. In a parody of the established "simulator" cliche, "Your Sinclair" released a game titled "Advanced Lawnmower Simulator" in 1988.
