What was the first first person video game?
First-person shooter
1998's "Half-Life"—along with its 2004 sequel "Half-Life 2"—enhanced the narrative and puzzle elements. In 1999, the "Half-Life" mod "Counter-Strike" was released and, together with "Doom", is perhaps one of the most influential first-person shooters. "GoldenEye 007", released in 1997, was a landmark first-person shooter for home consoles, while the "Halo" series heightened the console's commercial and critical appeal as a platform for first-person shooter titles. In the 21st century, the first-person shooter is the most commercially viable video game genre, and in 2016, shooters accounted for over 27% of all video game sales. Several first-person shooters have been popular games for eSports and competitive gaming competitions as well.
GoldenEye 007 (1997 video game)
Retrospectively, "GoldenEye 007" is considered an important game in the history of first-person shooters for demonstrating the viability of game consoles as platforms for the genre, and for signalling a transition from the then-standard "Doom"-like approach to a more realistic style. It pioneered features such as atmospheric single-player missions, stealth elements, and a console multiplayer deathmatch mode. The game is frequently cited as one of the greatest video games of all time. A spiritual successor, "Perfect Dark", was released in 2000, while a reimagining of the game, also titled "GoldenEye 007", was released in 2010.
