Colossal Cave Adventure
Colossal Cave Adventure, more commonly called Adventure and often described with the adjective "Crowther/Woods", was the first game in the interactive fiction (once called "text adventure") genre. It was developed by William Crowther and Donald Woods between 1976 and 1977, and there have been many variations and ports of the game since then.
Adventure was a key influence on Rogue, which was essentially the "travelling through a cave" model of Adventure as applied to traditional RPGs such as Dungeons & Dragons, using the Curses library to simulate movement (instead of entering compass directions as done in interactive fiction games).
