first motorbike simulator for its realism at the time, in both the handling of the player's motorbike and the AI of the computer-controlled motorcyclists. It used force feedback technology and was also one of the first arcade games to use 16-bit graphics and Sega's "Super Scaler" technology that allowed pseudo-3D sprite-scaling at high frame rates. Suzuki's team at Sega followed it with hydraulic motion simulator cabinets for later racing games, such as Out Run in 1986. In 1986, Konami released WEC Le Mans, an early car driving simulator based on the 24 Hours of Le Mans. It attempted to realistically simulate car driving, with the car jumping up and down, turning back and forth, and spinning up to 180 degrees, with an emphasis on acceleration, braking, and gear shifting, along with the need for counter-steering to avoid spin-outs. It also featured a day-night cycle, accurately simulated courses approved by the Automobile Club de l'Ouest, and force feedback to simulate road vibration in the form of a vibrating steering wheel that reacts to the driver's acceleration and off-road bumps. The first racing game with simulation pretensions on a home system is believed to have been Chequered Flag, released by Psion on the 8-bit ZX Spectrum in 1983. REVS, followed in 1986. REVS was a Formula 3 sim that delivered a semi-realistic driving experience by Geoff Crammond that ran on the Commodore 64 and BBC. REVS had a big fan base in England, but not so much in the United States. 3D polygon graphics appeared in arcade racing simulators with Namco's Winning Run (1988) and Atari's Hard Drivin' (1989), the latter also becoming a staple on home computers, where it was one of the most widely played simulators up to that point. During the late 1980s to early 1990s, arcade racing games such as Out Run and Virtua Racing (1992) had increasingly elaborate, hydraulic motion simulator arcade cabinets, with arcade racers such as Virtua Racing and Daytona USA (1993) increasingly focused on simulating the speed and thrills of racing. At the same time, arcade racing games gradually moved away from the more difficult simulation style of Pole Position. By the early 1990s, arcade racing games had less emphasis on realistic handling or physics, and more emphasis on fast-paced action, speed and thrills. Emergence of sim racing genre (1989–1997) Sim racing is generally acknowledged to have really taken off in 1989 with the
