The first computer adventure game came alive in a cave, called the Colossal Cave. Written by William Crowther, it set off an explosion of "look-alike" clones, though none remain as fanciful, as magical, or as wondrous as Colossal Cave, also known as Adventure. It represented a new kind of computer program -- a game of flowing, descriptive text portraying a wonderful story involving creatures,
treasures, and magic. Adventure is said to have inspired Dave Lebling, the creator of the ZORK games, to create adventure games.

But what exactly is Adventure?

You are an adventurer on a mission to collect a number of treasures, learn a variety of magic words, and solve a myriad of puzzles.
