About
Colossal Cave Adventure is a text adventure released by Will Crowther in 1976 for the PDP-10 and expanded by Don Woods in 1977, the first well-known work of interactive fiction. Open Adventure is a forward-port of Crowther and Woods' Adventure 2.5 from 1995, the last mainline version written by the original authors, released with their permission and encouragement. It obsoletes all 350-point versions and earlier 430-point ports, and is commonly packaged by Linux distributions as "open-adventure".
How it differs from the original
By policy, gameplay is not silently changed: every user-visible change from 2.5 that is not a bug or typo fix can be reverted with the -o (oldstyle) command-line option.
Getting started
Install it from your distribution's "open-adventure" package or download a tarball from the project homepage; a build guide is included in the repository.
History
The project is called Open Adventure because there was no clear way to number a version past 2.5 without causing confusion or name collisions.
Additional notes
- Trivia
- The executable uses the game's original 6-character PDP-10 name to avoid clashing with the BSD games port of the 1977 version.
- Bug reports
- Bug reports should include a reproducing test log recorded with the -l option.
