Answer
First-person shooter (FPS) games, where players experience the action through the eyes of the protagonist, were popularized by George A. Romero. Romero, known for his groundbreaking horror films, notably "Night of the Living Dead," is credited with pioneering the use of the first-person perspective in video games. His 1980 arcade game "Mad Dog McCree" introduced a realistic, immersive FPS experience, setting the stage for the development of the genre.
