Road Rash is a 1991 racing and vehicular combat video game developed and published by Electronic Arts (EA) for the Sega Genesis. It was subsequently ported to a variety of contemporary systems by differing companies. The game is centered around a series of motorcycle races throughout California that the player must win to advance to higher-difficulty races, while engaging in unarmed and armed combat to hinder the other racers.

Road Rash was one of the first games conceived by EA following the company's decision to begin developing games internally. The game's programmers Dan Geisler and Carl Mey were hired by EA to create a banked road effect for Mario Andretti Racing, then being developed as an NES title. When the NES hardware proved incapable of rendering the desired effect, focus shifted to a motorcycle racing game for the more powerful Sega Genesis. The game includes combat elements that were inspired by the violent behavior of Grand Prix motorcyclists during races, and the resulting uncertainty surrounding the game's genre created conflict between EA's development team and management.

Road Rash was released to critical and commercial success, and was EA's most profitable title to date. The original version for the Sega Genesis was particularly acclaimed for its violent and aggressive gameplay and the convincing sense of speed in its graphics. The game is the debut installment of the Road Rash series, and was followed by a number of sequels made for various consoles.

Gameplay

Road Rash puts the player in control of a motorcycle racer who must finish in fourth place or higher among fourteen other racers; the player advances throughout the game's five levels by winning five races on each level.Road Rash (Genesis) instruction manual, p. 13 The game is primarily single-player, but allows for two players to play intermittently against each other.Road Rash (Genesis) instruction manual, pp. 12–13 The game's races take place in a number of Californian settings, including Grass Valley, the Sierra Nevada, Napa Valley, and the Pacific Coast Highway.Road Rash (Genesis) instruction manual, pp. 17–18 During a race, the racer can brake, accelerate, and attack neighboring opponents. The racer will punch at the nearest opponent with a default input, while holding a directional button during the input will result in either a backhand or a kick. Some opponents wield clubs, which can be taken and used by the racer if the opponent is attacked as they are holding the club out to strike.Road Rash (Genesis) instruction manual, pp. 10–12 The racer can be ejected from their bike if they crash into an obstacle (such as cows, deer, cars, and treesRoad Rash (Genesis) instruction manual, pp. 18–19) or if they run out of stamina (shown in the bottom-left corner of the screen) due to fights with opponents.Road Rash (Genesis) instruction manual, pp. 9–10 In this event, the racer will automatically run back toward their bike, though the player can alter their course and avoid incoming traffic with the directional buttons, or stand still by holding the brake input button. Opponents will likewise be ejected from their bike if their own stamina is depleted; the stamina of the nearest opponent is visible within the bottom-right corner of the screen.

The racer begins the game with $1,000 and earns cash prizes for each successful race.Road Rash (Genesis) instruction manual, pp. 19–20 Between races, the player can access a shop and view several bikes of differing weights, speeds, and steering capabilities, and the player may purchase a new bike with the money they have accumulated.Road Rash (Genesis) instruction manual, pp. 16–17 The player will receive a password at the end of a successful race, which can be entered at a password entry screen in a subsequent session to maintain the player's progress;Road Rash (Genesis) instruction manual, pp. 14–15 The player will advance to the next level after winning a race on all five of the game's tracks. The player wins the game by winning a race on each track in all five levels.

The bike has its own "damage meter" between the racer's and opponents' stamina meters, which decreases every time the racer suffers a crash. The bike will be wrecked if the meter fully depletes, which ends the player's participation in the current race and deducts the cost of a repair bill from the racer's balance. Motor officers make sporadic appearances throughout the game's tracks, and can also end the player's participation if they apprehend the racer following a crash, which deducts the cost of a fine from their balance. If the racer lacks the funds to cover either a repair bill or a fine, the game will end prematurely.

Development and release Conception and early development Road Rash was one of the first titles conceived by EA after they made the decision to begin developing video games in-house; until that point, EA had previously outsourced video game development to external studios, and were primarily focused on PC games due to the effects of the video game crash of 1983. In its tentative steps back into the console market, EA focused on genres that were determined to be strategic, namely sports and racing titles. Preliminary development began on an NES title named Mario Andretti Racing, and programmer Dan Geisler was hired by the company at this time. Technical director Carl Mey, who had just been laid off from Epyx following its bankruptcy, was also hired by EA and was given his first major project of creating a "banked road" effect for the game. Mey soon realized that while the NES was capable of road-scaling effects, banking would be beyond the console's ability. Producer and designer Randy Breen, who was previously involved with Indianapolis 500: The Simulation, was influenced by the difficulty and tedium of that title to create a racing game with more accessibility and entertainment value. Because Andretti was set to follow a similar formula to Indianapolis 500, Geisler, Breen, May and co-designer Walter Stein began a brainstorming session for a different type of racing game that would not necessarily adhere to realism. After Mey and Geisler rejected QuadRunners as potential racing vehicles due to Andretti'''s dirt track setting, Breen suggested motorcycles. Breen recounted: "I'd been into motorcycles for a long time, and we quickly realized bikes gave us lots of technical advantages. For instance, we could put more bikes than cars onscreen at once, and the bikers were more visible than car drivers, so they could be more expressive". The game's title originated from Breen reminiscing to the group about riding his own bike on Mulholland Drive to meet with friends and thinking to himself: "Man, if you wiped out here, you'd get some serious road rash". Geisler suggested the title Road Rash on Mulholland Drive, and Breen used the name to pitch the concept to EA. The title was eventually shortened to Road Rash, and development moved from the NES to the recently introduced Sega Genesis, which was powerful enough to generate the desired road effects.

Before joining EA, Geisler had worked on Spectrum HoloByte's racing game Vette!; Geisler's coding for this title provided the framework for Road Rash, particularly its algorithm for estimating road curvature. Geisler claimed that the Genesis's memory capacity could have allowed him to create 802 miles of unique roads, and that he could have accurately mapped out the entire coast of California. The road effect for Road Rash took Geisler about six months to create, comprising a large portion of the game's early development. 3D-rendering technology for the game was adapted from the Genesis version of Blockout, which was in development at the same time. Lead artist Arthur Koch was brought onto the development team after the project was well underway, and he was tasked with training the other artists on using EA's in-house tools and conforming to the Genesis's 64-color palette, which Koch stated "was hard for a lot of artists to grasp". Several months into development, EA made the decision to promote Road Rash at the 1990 Consumer Electronics Show as a show of support for the Sega Genesis. This initial demonstration proved unsatisfactory; Breen recalled that they struggled to maintain a reasonable frame rate and the animations were ineffective. Mey also had concerns with "the very tame, almost Disney-like view of the AMA, and Randy's desire to make it a 'go anywhere'-style game". He remarked that the development team would refer to the game as "Randy's Sunday Ride" behind his back, and that "Road Rash needed more balls to sell than a simulation of someone following the speed limit". Following the show, the game needed to be re-pitched twice to avoid cancellation, and the team was given an additional six months to improve the game.

Revamp and release Mey requested to EA producer Richard Hilleman that he be given creative control over the gameplay on the grounds that he "wanted to make the game kick ass", to which Hilleman agreed. Over the following months, Geisler and Stein improved the game's performance, and Connie Braat refined the animation. To increase the player's sense of immersion, the rival racers were given individual names and characters, and would deliver banter in between races. The motor officers who pursue the player and arrest them if they crash were added to the game to create tension. To obtain reference material, Koch went to a local police department and convinced a motor officer to pose for photographs. The wipe-out animations were brought about by Koch's previous work on John Madden Football and Lakers versus Celtics and the NBA Playoffs; on the subject, Koch said: "I was disappointed with the tackles and the falls and the fouls. I thought they could be a lot more dynamic. So I suggested that we devote more frames of animation to the crashes". Breen cited additional influence from Wile E. Coyote and the Road Runner and "other cartoons where the villain gets beat up", adding that "even though it set you back, it was still fun to watch". The combat element of the game was inspired by the behavior of Grand Prix motorcyclists, who Breen noticed would sometimes shove and kick each other during races. Other influences on this aspect include the biker gang action scenes in Akira (1988) and the tire pump scene in Breaking Away (1979).
