Abstract
Because so little primary historical work has been done on the classic text computer game “Colossal Cave Adventure”, academic and popular references to it frequently perpetuate inaccuracies. “Adventure” was the first in a series of text-based games (“interactive fiction”) that emphasize exploring, puzzles, and story, typically in a fantasy setting; these games had a significant cultural impact in the late 1970s and a significant commercial presence in the early 1980s. Will Crowther based his program on a real cave in Kentucky; Don Woods expanded this version significantly. The expanded work has been examined as an occasion for narrative encounters [Buckles 1985] and as an aesthetic masterpiece of logic and utility [Knuth 1998]; however, previous attempts to assess the significance of “Adventure” remain incomplete without access to Crowther’s original source code and Crowther’s original source cave. Accordingly, this paper analyzes previously unpublished files recovered from a backup of Woods’s student account at Stanford, and documents an excursion to the real Colossal Cave in Kentucky in 2005. In addition, new interviews with Crowther, Woods, and their associates (particularly members of Crowther’s family) provide new insights on the precise nature of Woods’s significant contributions. Real locations in the cave and several artifacts (such as an iron rod and an axe head) correspond to their representation in Crowther’s version; however, by May of 1977, Woods had expanded the game to include numerous locations that he invented, along with significant technical innovations (such as scorekeeping and a player inventory). Sources that incorrectly date Crowther’s original to 1972 or 1974, or that identify it as a cartographic data file with no game or fantasy elements, are sourced thinly if at all. The new evidence establishes that Crowther wrote the game during the 1975-76 academic year and probably abandoned it in early 1976. The original game employed magic, humor, simple combat, and basic puzzles, all of which Woods greatly expanded. While Crowther remained largely faithful to the geography of the real cave, his original did introduce subtle changes to the environment in order to improve the gameplay.
When my dad got his first computer back in ’87 through a work sponsorship deal, he got a diskette from a cow-orker (one of those old floppy 51/4 inch ones) with oodles of classic games, including Adventure. The hours I’ve sat behind the pc with tracing paper and pencil to sketch my way through the maze. Once, when I was really, really bored at a job I might have even downloaded the VMS version of Adventure to the Alpha system I was working on as a way not to die of boredome waiting for something to do…
