Open Adventure

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.
