Adventure - Twisty Little Passages

Willie Crowther/BBN 1972 and Don Woods/SAIL 1973

You are in a maze of twisty passages, all alike.

Adventure aka ADVENT aka Colossal Caves is the next logical evolution of computer games, a complete text-based adventure game by Willie Crowther. It is written in FORTRAN on the venerable PDP-1 in 1972 while Crowther is working for Bolt, Beranek and Newman, Inc. (BBN). The Cambridge, Massachusetts company  is made up mostly of MIT students, and is awarded the contract to develop the ARPAnet for the U.S. government, a scheme to create communication and data links between all facilities doing military research. Crowther is also part of the software team for BBN’s IMP, or Interface Message Processor, the original nodes used to connect the ARPAnet, which eventually evolves into the Internet as the commercial ramifications of such a nationwide – and worldwide – network are unveiled. For his computer game, Crowther is inspired by the new fantasy themed paper-and-dice game Dungeons and Dragons which is extremely popular with the university crowd. More inspiration comes from his adventures as an avid spelunker. In Adventure, you must explore the vast Colossal Caves and return to the starting point with as many treasures as you can. The locations are based on his and his ex-wife’s exploration of the Mammoth Cave system in Kentucky, and their divorce is further impetus for Crowther to fill his time programming the game. Some fanciful D&D type magic is added into the mix for good measure.

In 1977, at the Stanford Artificial Intelligence Lab at Stanford University, the game is expanded on by Don Woods, with Crowther’s permission. The original parser in the game is a rudimentary “verb-noun” structure, but the location descriptions are very compelling. Again, access to the mainframe running the program through the ARPAnet allows the program to become very popular among university students across the country.

Adventure, in fact, becomes one of the most influential programs in computer and video gaming history. It would set the template for online multiplayer gaming in the form of MUDS and MOOS, allowing people from across the world to come to together, form communities, and embark on adventures together. For a shortlist of developers who are inspired by Adventure to beat a path to the burgeoning personal computer and video game scene:  Scott Adams creates Adventureland in the wake of playing the original, going on to found Adventure International. The MIT graduates of Infocom, who parlay their interest in Adventure into the seminal Zork interactive fiction series as well as dozens of other text adventures. Gordon Letwin, while working for Heath and authoring the HDOS operating system for the kit computer company, adapts the PDP-10 version of Adventure for microcomputers. Later, as one of the original 11 employees of Microsoft, he develops it into Microsoft Adventure for the TRS-80, and it becomes an early consumer product of the company in 1979, and ported to systems like the IBM-PC later. No less than Nolan Bushnell, the father of the video game industry, is a fan of the game in the early 70’s. There are other, countless players who fall into the time sink of Crowther and Wood’s world of exploration, and then set off to blaze their own trail in the industry. To end with some words Don Woods tells video game chronicler Steve Levy in 1983, when describing the impact of the game’s initial appearance on computers at Stanford: people would “enter the computer centre on a Friday afternoon and not leave until Monday.”  logo_stop
