Colossal Cave Adventure: Building and running 40-year-old code from the dawn of gaming

Created in 1977 by Willie Crowther and Don Woods, Colossal Cave Adventure may be the most influential computer game ever. With the combination of compelling game play and freely available source code, it spread from one data center to another in the pre-GUI, pre-Internet era.

This article shows you how to build and play the game.
