Type 'GO NORTH' and discover an entire genre hiding inside a text prompt.
Will Crowther, an avid caver and programmer at BBN, created Colossal Cave Adventure on a PDP-10 mainframe. The game was a text-based simulation of Kentucky's Mammoth Cave system, sprinkled with fantasy elements like dwarves and a magic bridge. Don Woods at Stanford later expanded it significantly. Players navigated entirely through typed commands, imagining every room from text descriptions alone. It spread across ARPANET and university computers, creating the adventure game genre and inspiring everything from Zork to modern interactive fiction.
Example
The game's opening line, 'You are standing at the end of a road before a small brick building,' became one of gaming's most iconic sentences. The command 'XYZZY' from the game became a universal geek password and Easter egg reference that persists in software to this day.
Why it matters
Colossal Cave Adventure invented the adventure game genre wholesale. It proved that games could be about exploration, puzzle-solving, and narrative rather than reflexes and scoring. Every RPG, adventure game, and interactive fiction title traces its lineage back to this cave.
