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".
Dungeons &amp; Dragons
"Dungeons & Dragons" was the first modern role-playing game and it established many of the conventions that have dominated the genre. Particularly notable are the use of dice as a game mechanic, character record sheets, use of numerical attributes and gamemaster-centered group dynamics. Within months of "Dungeons & Dragons"'s release, new role-playing game writers and publishers began releasing their own role-playing games, with most of these being in the fantasy genre. Some of the earliest other role-playing games inspired by "D&D" include "Tunnels & Trolls" (1975), "Empire of the Petal Throne" (1975), and "Chivalry & Sorcery" (1976).
