Colossal Cave Adventure, a 1976 text game, invented the adventure genre and much of interactive fiction

the gist

Colossal Cave Adventure was written in 1975 and 1976 by Will Crowther for the PDP-10 mainframe, and expanded in 1977 by Don Woods. The player explores a cave system full of treasure by typing short two-word commands like 'go north' or 'take lamp', and the program narrates each result. Crowther based the cave on his caving trips in Kentucky's Mammoth Cave, and wrote it partly so his daughters could play. Woods added fantasy elements such as a dragon and magic spells. Both versions spread across the early ARPANET, and the game became the template for interactive fiction, adventure games, roguelikes and MUDs.

how it works

The game parsed typed commands into a small vocabulary of verbs and nouns, then looked up the matching response in a database of locations and objects. It tracked the player's position and inventory as state, so each command changed what was possible next. This simple pattern of world state plus parsed text became the core structure of later games.

so what

Nearly every text adventure, roguelike and role-playing game descends from this program, which made it one of the most influential games ever made. It showed that a computer could tell a story and respond to natural-language commands decades before graphics made games visual.

the bigger pattern

Interactive fiction grew from this 1976 game into the Zork series and the wider adventure and roguelike genres. Its influence on game design is a long chain: each generation of text and graphical adventures reused its basic loop of exploring, collecting and solving puzzles.
