Eamon, sometimes known as The Wonderful World of Eamon, is a game creation system and a role-playing adventure game series created by Donald Brown and released for the Apple II in 1980. The game is a text adventure similar to other early titles like Adventure (1976) or Zork (1980) and to later text-based multi-user dungeons (MUDs), though with many role-playing elements not available in other interactive fiction. Eamon software is non-commercial and is freely available in the public domain. Premise Eamon casts the player in the role of a free-wheeling fantasy adventurer who undertakes dangerous quests against numerous enemies to earn riches and experience. Home base is the Guild of Free Adventurers, an association of heroes on the mystical world of Eamon, a vaguely Medieval place awash in magic and populated with strange creatures. Most adventures take place in the dungeons, castles and forests of Eamon, though some occur on other worlds or in different eras. Eamon creator Donald Brown described Eamon as "a world at the center of another galaxy—instead of revolving around any star, all of the stars revolve around it! Those huge bodies exert strange effects on the world of Eamon, bending light, gravity, time, even the laws of nature themselves!" Though influenced by such fantasy environments as Dungeons & Dragons and The Lord of the Rings, Eamon generally avoids stories, situations or other game elements that are particularly serious or complex, instead seeking to create an engaging, genial mood through quick play and in-jokes. Individual adventures, created by a wide range of authors, vary from the artful to the campy. The game's splash page (see infobox) uses the same image used for the title screen of the Robert Clardy game, Odyssey: The Compleat Apventure. Gameplay Brown encouraged players to modify and add to Eamon, and published technical information on the game to assist them. Eamon is notable for being one of the first adventure games designed to be modular, with expansion packs written by users forming an integral part of the game experience. A master disk called the "Main Hall" is used to manage player characters and to facilitate their transfer between individual adventures. The character retains his or her attributes and statistics from adventure to adventure, as well as up to four weapons. The game's interface is similar to that of most other text adventures — the game presents the player with descriptions of the
