The game was created by Will Crowther, a caving enthusiast, who combined a faithful simulation of his cave explorations and elements of fantasy role playing (he was a fan of Dungeons and Dragons), to create an adventure game for his daughters.
While there were other text based computer games before Adventure like STARTREK (incidentally our first release - Star Trek Classic), this was the first text based 'interactive fiction' game. Colossal Cave Adventure brings to Windows the game that started it all - the game that pioneered the computer adventure game genre.
