Hunt the Wumpus has been cited as an early example of a survival horror game; the book Vampires and Zombies claims that it was an early example of the genre, while the paper "Restless dreams in Silent Hill" states that "from a historical perspective the genre's roots lie in Hunt the Wumpus".[16][17] Other sources, however, such as the book The World of Scary Video Games, claim that the game lacks elements needed for a "horror" game, as the player hunts rather than is hunted by the Wumpus, and nothing in the game is explicitly intended to frighten the player, making it more of an early adventure or puzzle game.[18] Kevin Cogger of 1Up.com claimed that Wumpus, whether or not it is an adventure game, "introduced a number of concepts that would come to define the adventure genre", such as presenting the game from the perspective of the player-character, and non-grid-based map design.[19] In 2012, Hunt the Wumpus was listed on Time's All-Time 100 greatest video games list.[20] The Wumpus monster has appeared in several different forms of media, including a "Hunted Wumpus" Magic: The Gathering card,[21] the 1983 video game M.U.L.E.,[22] and Cory Doctorow's 2011 novella The Great Big Beautiful Tomorrow.[23] The textbook Artificial Intelligence: A Modern Approach, with editions published since 1995, uses a version of this game as one of the examples.[24]
