    rFactor is a computer racing simulator, designed with the ability to run any type of four-wheeled vehicle from street cars to open wheel cars of any era. rFactor aimed to be the most accurate race simulator of its time. Released in November 2005, rFactor did not have much competition in this market; however it featured many technical advances in tire modeling, complex aerodynamics and a 15 degrees of freedom physics engine.

    rFactor was developed by Image Space Incorporated (ISI), which has been developing simulators since the early 1990s for both commercial and military purposes. The isiMotor2 on which the game is based is a direct successor to the engine used in previous titles developed by ISI, most notably F1 Challenge '99-'02, released through EA Sports. The isiMotor2 engine was also used in many Simbin games, including GT Legends, the GTR series and the Race series. A modified version of this engine was utilized by The Sim Factory for ARCA Sim Racing. A special version of rFactor was available for business application, for example for event simulators or promotion.

    Gameplay

    rFactor has a detailed interface during offline race sessions or online games, allowing players to control the mechanical setup of their cars, chat to other players, and enter the racing arena in their vehicle. The player's car can be driven from multiple viewpoints, but the two most popular are termed the cockpit view (from the driver's eye) and swingman view (above and behind the vehicle).

    Most players say vehicles are best controlled using a computer steering wheel, although a joystick or even keyboard can be used. The keyboard is also used for some actions, like requesting pit service and adjusting brake bias. This is analogous to buttons on modern racing car steering wheels, and most computer wheels have buttons that can be mapped to keystrokes. The player can jump directly from the racetrack to the control interface by pressing the escape key (ESC), or entering their pit box.

    Vehicles and circuits

    rFactor has two classes of vehicles, "Open Wheel Challenge" and sedan cars. Open Wheel Challenge vehicles are open wheelers, including 100 HP training vehicles, F3-like cars and F1-like cars (called FormulaIS). The sedan cars range from compact but sporty to BMW-like vehicles and US Muscle cars; they also include stock cars (USAR-like).

    ISI announced (in 10 May 2006) a deal with Intel to add the BMW Sauber Formula One car to the game. The vehicle was demonstrated at the 2006 European Grand Prix. The deal was to be specifically to promote the upcoming Intel Core 2 processor. [1]. The BMW Sauber was added in 2006. The respective cars of 2007 and 2008 were released as official add-on.

    Developer ISI did not seek to license any series at all, so included only fictitious circuits and vehicles. rFactor was released with just five facilities, comprising approximately 10 layouts, including some which were simply reverse races. The facilities were Orchard Lake (an oval and road course), Mills Park and Toban Raceway (road courses), Joesville Runabout (a short oval) and Sardian Heights (a street race in a city environment). In later updates an extra layout for Sardian Heights have been added, Essington Park, Lienz (a mountain road and rally course) and Jacksonville (a high banked super speedway) were added. Several real world tracks, but with fictitious names, were added to the game as part of an update released in 2006, such as Barcelona (Circuit de Catalunya, Spain), Brianza (Autodromo Nazionale Monza), Northamptonshire (Silverstone Circuit) and Nuerburg (Nürburgring).

    Modifications

    In addition to the stock vehicles and circuits available in rFactor, a steady stream of unofficial mods has become available. One of the earliest mods was F3 vehicle mod, which became very popular for some time and was later officially included in the game, although with fictitious branding. Many more modifications were released, including ones that recreated seasons from Formula One, NASCAR, IndyCar and V8 Supercars. Cars from the racing games Forza Motorsport, Shift 2 Unleashed, and Test Drive Unlimited were also converted into rFactor with the mod Shift Street. The mod now has over 200 cars from other racing games. With the release of the SDK many new venues were created and released as unofficial addons to the game. Many of the circuits for rFactor were converted from other games, including GTR, GT Legends, TOCA Race Driver, Grand Prix 4 and GP Legends.

    Development

    rFactor is an evolution of F1 Challenge '99-'02, but without the licensing of Formula One circuits and teams. As such rFactor's initial release only included four fictitious circuits (seven as of v1.087), with about a dozen layouts within these facilities; there are about six vehicle classes, including two open wheel and four sedan classes. Among its most notable features was a rich interface for creating custom game contents, which made it possible for amateurs to create additional vehicles and tracks for the game. On August 1, 2006, ISI released the full update,[1] with many changes and new features, including the new 2006 BMW Sauber F1 and a much requested manual. Another notable and often requested feature was driver-swapping, which allowed to change drivers during the race, enabling up to 24 hour events like Le Mans.

    A feature was added to allow the AI to "learn a track", which teaches the AI the ideal way to drive a particular circuit. As of v1.150, the AI was improved, leading to notably faster driving styles. rFactor also advertises an advanced tire model, aiming to be much better than the Pacejka model previously used in most simulators. rFactor's tire model simulates a non-linear tire use cycle according to temperature and wear.[citation needed]

    F1 Challenge proved to be popular for online racing over the Internet through GameSpy, which allowed any player to find available games. rFactor has extended this in several ways. The central server is handled by ISI themselves, so finding other games is effectively the same. The central server, however, will show all races and practice sessions over a web interface known as Racecast.[2] There are also career statistics available for registered drivers. The game server can be run from a dedicated program, free from the need to render graphics. It can run mixtures of human and computer controlled (AI) vehicles.

    In an evolution from F1 Challenge, the circuits now include all layouts at a particular facility, which greatly reduces the need to duplicate track geometry. The game can easily accommodate different sorts of vehicles, and games between multiple classes of vehicles are possible. rFactor also has a plugin-interface for third-party addons to hook in. This allows for features like screen-overlays or radio chatter.[citation needed]

    In the first review of rFactor[when?], published on AutoSimSport, Jon Denton stated:

    What the tire model in rFactor does very well is that it models the relationship between slip angle, self aligning torque and cornering force - and it does this better than anything that has come before.[5]

    Writing on honestgamers, Paul Josua concluded "It’s a little unfair to hold rFactor’s lack of accessibility against it as it has clearly set out to be a simulation racer. It does a fine job of that, but those who don’t demand flawless simulation are better served looking elsewhere."

    Sequel

    In March 2009 ISI announced the development of rFactor 2, which will include weather effects, reflections, and accurate shadows on a variety of textures.[6]
