 In 1985, Sega's third-person arcade rail shooter game "Space Harrier" introduced a true analog flight stick, used for movement.The joystick could register movement in any direction as well as measure the degree of push, which could move the player character at different speeds depending on how far the joystick was pushed in a certain direction.A distinct variation of an analog joystick is a positional gun, which works differently from a light gun.
