Mecha simulation

Vehicle simulation games are a genre of video games which attempt to provide the player with a realistic interpretation of operating various kinds of vehicles. This includes automobiles, aircraft, watercraft, spacecraft, military vehicles, and a variety of other vehicles. The main challenge is to master driving and steering the vehicle from the perspective of the pilot or driver, with most games adding another challenge such as racing or fighting rival vehicles. Games are often divided based on realism, with some games including more realistic physics and challenges such as fuel management.

Vehicle simulation games allow players to drive or fly a vehicle. This vehicle can resemble a real one, or a vehicle from the game designer's imagination. This includes vehicles in the air, on the ground, over water, or even in space. Different vehicle simulations can involve a variety of goals, including racing, combat, or simply the experience of driving a vehicle. These games normally allow the player to experience action from the visual perspective of the pilot or driver. Although "racing games are often sold in the sports category," Rollings and Adams argue that "from a design standpoint, they really belong in ... vehicle simulations".

The essential gameplay in a vehicle simulation is the physical and tactical challenge of driving a vehicle. Mastery of vehicle control is the element which encourages players to continue playing, even after the game's goals have been completed. Players learn to use appropriate speed and steering, and must avoid crashing by observing cues about how fast they are going. There are some vehicle simulations where the player is given no specific goal, and is simply able to explore and experience using the vehicle. In the absence of any competition, "some vehicle simulations aren't games at all"

But most vehicle simulations involve some form of competition or race, with a clear winner and loser. Some games add special challenges such as combat and . Many types of driving games, including both military flight simulators and racing simulators, make use of careers and campaigns. Players must complete different tracks or missions, and collect victories and other achievements based on their performance.

The market for vehicle simulators is "divided between the purists and the casual players". A variety of vehicle simulators have been created to serve both markets. Purists demand total accuracy, whereas casual players are less concerned with such details. This level of accuracy depends on how damage, physics, environment, weather, and controls are implemented. For example, accurate flight simulators will ensure that the vehicle responds slowly to their controls, while other games will treat the plane more like a car in order to simplify the game.
