What was the first first person video game?
First-person (gaming)
While light gun shooters often have a first-person perspective, they are distinct from first-person shooters, which use conventional input devices for movement.[4] 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.[5] 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).[5]
Video game
Early games used interactive electronic devices with various display formats. The earliest example is from 1947—a "Cathode ray tube Amusement Device" was filed for a patent on 25 January 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on 14 December 1948, as U.S. Patent 2455992. Inspired by radar display technology, it consisted of an analog device that allowed a user to control a vector-drawn dot on the screen to simulate a missile being fired at targets, which were drawings fixed to the screen. Other early examples include: The Nimrod computer at the 1951 Festival of Britain; "OXO" a tic-tac-toe Computer game by Alexander S. Douglas for the EDSAC in 1952; "Tennis for Two", an electronic interactive game engineered by William Higinbotham in 1958; "Spacewar!", written by MIT students Martin Graetz, Steve Russell, and Wayne Wiitanen's on a DEC PDP-1 computer in 1961; and the hit ping pong-style "Pong", a 1972 game by Atari. Each game used different means of display: NIMROD used a panel of lights to play the game of Nim, OXO used a graphical display to play tic-tac-toe "Tennis for Two" used an oscilloscope to display a side view of a tennis court, and "Spacewar!" used the DEC PDP-1's vector display to have two spaceships battle each other.
