William Crowther & Don Woods - Collosal Cave Adventure

Adventure (as it was known in various versions) is an early text- based computer game. Made at a time before detailed graphics, the computer acts as your 'eyes and ears', describing your surroundings to you in text format. Using simple commands like "walk forward" to explore the cave, the game space is completely imagined by the player while navigating. Yet in a strange twist, the game is based on the layout of an actual cave in Kentucky, USA - that avid Adventure players report navigating with ease on their first visit.
