Zork is one of the earliest interactive fiction computer games of the twentieth century. It was marketed in 1979 after being created in the 70s by former MIT students. The game has been adapted to book series.
Settings: the video game sets in the ruins of an ancient empire lying far underground. The player is meant to search for adventure and wealth. He will have the goal to return to earth with the treasures and will inherit the title of Dungeon Master.
Commands: the game supports and understand common verbs and sentences such as “put the lamp and sword in the case”, “drop all except lantern”, “take”, “attack”, “climb”, “close”, “open”, etc. Some letters like “n, s, e, w, u, a, i, d” are short commands to achieve some actions.
Zork Trilogy: the game gathers a series of three original Zork which are Zork I: The Great Underground Empire (release in 1980, Infocom), Zork II: The Wizard of Frobozz (1981) and Zork III: The Dungeon Master (1982). These series are related to each other and cannot be played but chronologically.
Zork is a bit like an historical game that was often imitated but never duplicated.
It is played in command lines via computer terminals.
