First person perspective

In video games, the first person refers to a graphical perspective rendered from the viewpoint of the player's character. In many cases, this may be the viewpoint from the cockpit of a vehicle. Many different genres have made use of first-person perspectives, ranging from adventure games to flight simulators. The most notable genre to make use of this device is the first-person shooter, where the graphical perspective has a heavy impact on gameplay.

Games with a first-person perspective are usually avatar-based, wherein the game displays what the player's avatar would see with the avatar's own eyes. Thus, players typically cannot see the avatar's body, though they may be able to see the avatar's weapons or hands. This viewpoint is also frequently used to represent the perspective of a driver within a vehicle, as in flight and racing simulators; and it is common to make use of positional audio, where the volume of ambient sounds varies depending on their position with respect to the player's avatar.

Games with a first-person perspective do not require sophisticated animations for the player's avatar, nor do they need to implement a manual or automated camera-control scheme as in third-person perspective. A first-person perspective allows for easier aiming, since there is no representation of the avatar to block the player's view. However, the absence of an avatar can make it difficult to master the timing and distances required to jump between platforms, and may cause motion sickness in some players.

Players have come to expect first-person games to accurately scale objects to appropriate sizes. However, key objects such as dropped items or levers may be exaggerated in order to improve their visibility.

While many games featured a side-scrolling or top-down perspective during the 1970s and 80's, several early games attempted to render the game world from the perspective of the player.

While light gun shooters often have a first-person perspective, they are distinct from first-person shooters, which use conventional input devices for movement. It is not clear exactly when the earliest such first-person shooter video game was created. There are two claimants, Spasim and Maze War. The uncertainty about which was first stems from the lack of any accurate dates for the development of Maze War—even its developer cannot remember exactly. In contrast, the development of Spasim is much better documented and the dates more certain. The initial development of Maze War probably occurred in the summer of 1973. A single player made their way through a simple maze of corridors rendered using fixed perspective. Multiplayer capabilities, with players attempting to shoot each other, were probably added later in 1973 (two machines linked via a serial connection) and in the summer of 1974 (fully networked).
