A Duck-Dragon, a Chalice, and the First Great Quest

Somewhere in a golden maze, a dragon that looks unmistakably like a duck is guarding a chalice, and you — a single brave square — must bring it home. Adventure for the Atari 2600 took the text quests of university mainframes and painted them in light, handing players a sword, a key, and a world that stretched beyond a single screen.

Warren Robinett built the first true action-adventure and then hid a second gift inside it: a secret room bearing his own name, the first widely known Easter egg. Atari refused to credit its designers, so Robinett signed his work the only way he could — by making the signature itself a treasure to be found. Players wrote letters describing the hidden room, and a tradition was born.

Every lantern-lit dungeon since carries a little of Adventure's torchlight. The inventory, the roaming foes, the world map folded into a cartridge — it is all here, rendered in squares and courage. The duck-dragons were never the point. The point was that a world could fit inside a machine, and you could be lost in it, happily, for hours.
