The Zork video game series is a classic text-based adventure game series that began in 1980. The games are set in a fantasy world and are characterized by their challenging puzzles, immersive storytelling, and humorous tone. The games were known for their innovative use of language processing technology, which allowed players to interact with the game world using natural language commands. By 1986, Infocom, the developers and publishers of Zork merged with Activision. After this merger, new Zork games were no longer text adventures but graphical adventure games which many fans of the original series felt like Activision abandoned what made Zork popular. Despite their age, the Zork games remain popular with retro gaming enthusiasts and continue to influence the development of modern adventure games.
