 rendered from the viewpoint of the player 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. Perhaps the most notable genre to make use of this device is the first-person shooter

Game mechanics

Games with a first-person perspective are usually avatar
Avatar (computing)
In computing, an avatar is the graphical representation of the user or the user's alter ego or character. It may take either a three-dimensional form, as in games or virtual worlds, or a two-dimensional form as an icon in Internet forums and other online communities. It can also refer to a text...

-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, and do not 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

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.

. 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).

Spasim was originally developed in the spring of 1974. Players moved through a wire-frame 3D universe, with gameplay resembling the 2D game Empire. Graphically, Spasim lacked even hidden line removal, but did feature online multiplayer over the worldwide university-based PLATO network. Another notable PLATO FPS was the tank game Panther, introduced in 1975, generally acknowledged as a precursor to Battlezone. Spasim had a documented debut at the University of Illinois in 1974. The game was a rudimentary space flight simulator
