Is That A Dragon or a Duck?

Adventure – based on the classic text game of the same name – was the first game ever to contain an easter egg.
It seems laughably primitive these days, but when it first hit shelves, Adventure was a programming masterpiece. The text version of Adventure (by Willie Crowther and Don Woods) required hundreds of KB and a mainframe computer to operate, so much that Atari told Warren Robinett not to even bother with a 2600 version. He did anyway, and the results are near legendary. The 2600 version of Adventure went on to sell over a million copies at $25 a pop. For his effort Robinett recieved absolutely nothing beyond his $22,000/year salary.
Play the 2600 Adventure. (Flash) If you’re one of those who requires some eye candy, why not download the Quake 3 Adventure Map, instead?
