Adventure game
An adventure game is a video game in which the player assumes the role of a protagonist in an interactive story driven by exploration and puzzle-solving. The genre's focus on story allows it to draw heavily from other narrative-based media, literature and film, encompassing a wide variety of literary genres. Many adventure games (text and graphic) are designed for a single player, since this emphasis on story and character makes multi-player design difficult. "Colossal Cave Adventure" is identified as the first such adventure game, first released in 1976, while other notable adventure game series include "Zork", "King's Quest", "The Secret of Monkey Island", and "Myst".

These games evolved throughout subsequent decades, culminating in Sega's "Periscope", the company's first successful game released in 1966, which required the player to target cardboard ships. "Periscope" was an early electro-mechanical game, and the first arcade game to cost a quarter per play. Sega's 1969 game "Missile" featured electronic sound and a moving film strip to represent the targets on a projection screen, and their 1972 game "Killer Shark" featured a mounted light gun that shot at targets whose movement and reactions were displayed using back image projection onto a screen. Nintendo released the Beam Gun in 1970 and the Laser Clay Shooting System in 1973, followed in 1974 by the arcade game "Wild Gunman", which used video projection to display the target on the screen. In 1975, Sega released the early co-operative light gun shooters "Balloon Gun" and "Bullet Mark".
