The Atari 2600 game "Adventure" is considered one of the first graphic action/adventure games ever created. Personally, I have extremely fond memories of playing the game for the first time.

Creator Warren Robinett will be revealing how he got the pioneering game to fit into only 4K of memory during an upcoming post mortem presentation on the game at the Game Developer's Conference.

While "Adventure" looks primitive by today's standards, it was an amazing feat for the time, featuring things like hidden Easter eggs and even "desires" and "fears" for the in-game enemies... an early version of artificial intelligence. It will be interesting to hear how Robinett accomplished all this reportedly with less than a dozen pages of programming code.

Nearly every action/adventure and role playing game to follow owes a huge debt of gratitude to "Adventure," particularly Nintendo's wildly successful "Legend of Zelda" series.

Game Developer's Conference will be held on March 2-6 at the Moscone Convention Center in San Francisco. Thanks to Gamasutra for the tip.
