Adventure is a pioneering action-adventure video game released for the Atari 2600 in 1979, designed by Warren Robinett. As one of the earliest games in the adventure genre, players navigate a fantastical world depicted in simple graphics, represented by a square avatar on a quest to find a magical chalice and return it to the golden castle. The game is notable for its open-ended gameplay, featuring explorable mazes, various items to collect, use, or return, and enemies like dragons and bats. Its non-linear play and item interaction set the stage for future games in the adventure genre.
