The Second World War brought about one of the most significant advancements in technology in recorded history. Decades after the conflict ended, the world’s superpowers began working with advanced machines capable of expediently conducting calculations. These machines were eventually named computers. In the 1960s, the Advanced Research Projects Agency (ARPA), a branch within the United States Department of Defense invented a packet-switching network. Named the Advanced Research Projects Agency Network (ARPANET), it was the first network to implement the TCP/IP protocol suite. Government agencies would use this internetworking process to quickly share important information in a secure manner.
One of the programmers who helped develop ARPANET was Will Crowther. In his spare time, he and his wife Pat would frequently go spelunking. Mr. Crowther had previously helped create vector map surveys of the Mammoth Cave system in Kentucky for the Cave Research Foundation. He was also a fan of Dungeons & Dragons, a tabletop role-playing game that launched its first edition in 1974. These good times weren’t to last, for he ended up divorcing his wife in 1975. Striving to find some way to connect with his daughters following the separation, Mr. Crowther had an idea. Combining his fondness for cave exploration with his programming expertize, he decided to create a computerized simulation of his travels.
Development of this project began in 1975 and took a year to complete. It consisted of nearly 700 lines of FORTRAN code with another 700 written for BBN’s PDP-10 timesharing computer. The result was considered the first known instance of interactive fiction. The executable file for this program was called ADVENT, but the opening screen provided its more famous name: Colossal Cave Adventure. One person who discovered Mr. Crowther’s work was Don Woods – a recent graduate from Stanford University. Mr. Woods added his own ideas to the code, including a scoring system and high fantasy elements – the latter of which was inspired by his fondness of the writings of J.R.R. Tolkien.
Unlike Mr. Crowther’s original version, the source code of Mr. Woods’s was widely distributed. What started off as a way for a man to connect with his daughters became ground zero for a type of entertainment the public later dubbed adventure games. As computers became more commonplace in the average household, Colossal Cave Adventure became a great success. Even those with limited programming knowledge could enjoy playing this game, and its impact on the medium cannot be denied. In an era before people regularly used the term “video game”, how does Colossal Cave Adventure hold up?
