His work expanded Crowther's game to approximately 3000 lines of code and 1800 lines of data. He also introduced a scoring system within the game, and added ten more treasures to collect in addition to the five in Crowther's original version. Woods added upon Crowther's code in FORTRAN to include more high fantasy-related elements based on his love of J.R.R. Woods wanted to expand upon the game, and contacted Crowther to gain access to the source code. One of those that had discovered the game was Don Woods, a graduate student at Stanford University in 1976. Though titled in-game as Colossal Cave Adventure, its executable file was simply named ADVENT, which led to this becoming an alternate name for the game. During that time, others had found the game and it was distributed widely across the network, which had surprised Crowther on his return. Once the game was complete, Crowther showed it off to his co-workers at BBN for feedback, and then considered his work on the game complete, leaving the compiled game in a directory before taking a month off for vacation. Crowther's original version did not include any scorekeeping. It required about 60k words (nearly 300kB) of core memory, which was a significant amount for PDP-10/KA systems running with only 128k words. On the PDP-10, the program loads and executes with all its game data in memory. The data included text for 78 map locations (66 actual rooms and 12 navigation messages), 193 vocabulary words, travel tables, and miscellaneous messages. ![]() Crowther later commented that this approach allowed the game to appeal to both non-programmers and programmers alike, as in the latter case, it gave programmers a challenge of how to make "an obstinate system" perform in a manner they wanted it to.ĭeveloped over 19, Crowther's original game consisted of about 700 lines of FORTRAN code, with about another 700 lines of data, written for BBN's PDP-10 timesharing computer. He created a means by which the game could be controlled through natural language input so that it would be "a thing that gave you the illusion anyway that you'd typed in English commands and it did what you said". Following his divorce from Pat in 1975, Crowther wanted to connect better with his daughters, and decided a computerized simulation of his cave explorations with elements of his role-playing games would help. Roberts and Dave Lebling, one of the future founders of Infocom. In addition, Crowther enjoyed playing the tabletop role-playing game Dungeons & Dragons with a regular group which included Eric S. Crowther and his wife Pat were experienced cavers, having previously helped to create vector map surveys of the Mammoth Cave in Kentucky in the early 1970s for the Cave Research Foundation. Will Crowther was a programmer at Bolt, Beranek & Newman (BBN), and helped to develop the ARPANET (a forerunner of the Internet). The ultimate goal is to earn the maximum amount of points (350 points), which partially correlates to finding all the treasures in the game and safely leaving the cave. The game has a point system, whereby completing certain goals earns a number of predetermined points. A notable example is when the player dies after falling into a pit (player's commands in lower case, and the program's reply in all-capitals).go westYOU FELL INTO A PIT AND BROKE EVERY BONE IN YOUR BODY!NOW YOU'VE REALLY DONE IT!

Program's replies are typically in a humorous, conversational tone, much as a dungeon master would use in leading players in a tabletop role-playing game.

The program acts as a narrator, describing to the player what each location in the cave has, the results of certain actions, or if it did not understand the player's commands, asking for the player to retype their actions. To explore the cave, the player types in one- or two- word commands to move their character through the cave, interact with objects in the cave, pick up items to put into their inventory, and other actions. Adventure has the player's character explore a mysterious cave that is rumored to be filled with treasure and gold.
