Colossal Cave Adventure was the adventure game that gave the genre its name. It was also known as Colossal Cave, Adventure in Humongous Cave, Adventure, or ADVENT. The latter is due to the 6 character limit of computers at the time. It was a complete text adventure with no graphics, since the computer it was originally written for had no graphic output.
Gameplay
The game had the elements that would become a staple of the adventure genre, such as story-based gameplay, puzzles, and inventory. It had a point-based system, where you're awarded a number of points out of a possible total, based on whether you accomplished certain tasks in the game.
Development
Will Crowther developed Colossal Cave Adventure from 1975 to 1976 using the PDP-10 owned by his employer, Bolt Beranek and Newman, in FORTRAN IV. This was shared over the ARPANET, the precursor to the internet, of which Crowther was part of the development team.
In 1977, Don Woods found it, converted it to FORTRAN-10, and expanded it with Will Crowther's permission, completing his version later that year. Also in 1977, it was ported to C for UNIX by Jim Gillogly. The Crowther and Woods version became quite popular, inspiring many others to create their own games in a similar style.
Inspiration
There were text-based games were released before it, such as Hunt the Wumpus, which was created in 1973. Hunt the Wumpus was known for its bats which would transport the player to another room, which also appear in Colossal Cave Adventure. However, Colossal Cave Adventure is the adventure game that popularized the genre, and included an inventory and puzzles, which remain a staple in most western adventure games to this day.
The cave in Colossal Cave Adventure is based on Bedquilt Cave, a cave within the Mammoth Cave system in Kentucky, that connects to Colossal Cave. In 1972, Will Crowther's then-wife Patricia was part of the team that found the link that connected Flint Ridge caves to the Mammoth Cave. The Bedquilt cave was Will's favorite part of the Mammoth cave system, so after his divorce to Patricia, he decided to make a game based around it from a map he had made, in the hopes that it would be a game that his daughters would enjoy. As he was a fan of Dungeons and Dragons, he decided to combine elements of fantasy role-playing into the game as well. In the game, you search for treasure while navigating the maze-like caverns and avoiding or fighting the creatures.
Versions
Will Crowther's original version
The original FORTRAN IV version of Colossal Cave Adventure by Will Crowther, before it was continued by Don Woods, was discovered in a tape backup of Don Woods' student account at Stanford in 2005. The date of this version, March 11, 1977, reflects the point when Don Woods first discovered the game and saved it to his student account.

Legacy
The version by Will Crowther and Don Woods spread all over the ARPANET, inspiring many others, such as Sierra, Infocom, and Adventure International.
The point system would be used in the games by the companies that were formed in which the founders were inspired by the game. Sierra, in particular, continued the point system well into the graphical point-and-click era of adventure gaming.
