Wolfenstein 3D, released in 1992 by id Software, is widely considered to be the grandfather of the first-person shooter (FPS) genre in video games. The game, developed by John Carmack, John Romero, and Tom Hall, was a revolutionary title that set the standard for many FPS games to come.

Before Wolfenstein 3D, FPS games were not very popular and were mostly limited to text-based adventures or simple 2D graphics. However, the game's use of 3D graphics, combined with fast-paced action and intense violence, quickly made it one of the most popular games of its time. The game's success helped to establish the FPS genre as a major player in the gaming industry and laid the foundation for future games such as Doom, Halo, and Call of Duty.

One of the key innovations of Wolfenstein 3D was its use of 3D graphics. The game used a technique called ray casting, which allowed for the creation of 3D environments in real-time. This was a significant advancement in video game technology at the time, as it allowed players to move freely through the game's levels and see the world from a first-person perspective. This immersive experience was a major factor in the game's popularity and helped to establish the FPS genre as a staple of the gaming industry.

Wolfenstein 3D also popularized the use of violence in video games. The game's objective was to fight through hordes of Nazi soldiers and other enemies in order to escape from a prison camp. The game's graphic violence and blood was considered shocking at the time, but it helped to establish the FPS genre as a form of entertainment that could be both thrilling and challenging. The game's violence also helped to establish the game as a "mature" title, which helped to attract older players to the genre.

The game's success also helped to establish id Software as one of the most influential game development studios in the industry. The company's next game, Doom, was released the following year and was even more successful than Wolfenstein 3D. Doom's success solidified the FPS genre as a major player in the gaming industry and helped to establish id Software as a major player in the industry.
