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".

As one of the earliest shooter games, it set precedents and helped pave the way for future titles and for the shooting genre. "Space Invaders" popularized a more interactive style of gameplay with the enemies responding to the player controlled cannon's movement. It was also the first video game to popularize the concept of achieving a high score, being the first game to save the player's score. It was also the first game where players had to repel hordes of creatures, take cover from enemy fire, and use destructible barriers, in addition to being the first game to use a continuous background soundtrack, with four simple chromatic descending bass notes repeating in a loop, though it was dynamic and changed pace during stages. It also moved the gaming industry away from "Pong"-inspired sports games grounded in real-world situations towards action games involving fantastical situations. "Space Invaders" set the template for the shoot 'em up genre, with its influence extending to most shooting games released to the present day, including first-person shooters such as "Wolfenstein", "Doom", "Halo" and "Call of Duty".
