Space Harrier is a third-person arcade rail shooter game developed by Sega and released in 1985. It was originally conceived as a realistic military-themed game played in the third-person perspective and featuring a player-controlled fighter jet, but technical and memory restrictions resulted in Sega developer Yu Suzuki redesigning it around a jet-propelled human character in a fantasy setting. The arcade game is controlled by an analog flight stick while the deluxe arcade cabinet is a cockpit-style linear actuator motion simulator cabinet that pitches and rolls during play, for which it is referred as a taikan (体感) or "body sensation" arcade game in Japan.

1985 saw many sequels and prequels in video games, such as Super Mario Bros. and Kung Fu, along with new titles such as Commando, Duck Hunt, Gauntlet, Ghosts 'n Goblins, Gradius, Hang-On, Space Harrier, Tetris and The Way of the Exploding Fist. The year's highest-grossing arcade video games were Hang-On and Karate Champ in the United States, and Commando in the United Kingdom. The year's best‑selling home system was the Nintendo Entertainment System (Famicom) for the second year in a row, while the year's best‑selling home video game was Super Mario Bros.
