Adventure – based on the classic text game of the same name – was the first game ever to contain an easter egg. —Is That A Dragon or a Duck? (Metafilter)
It’s great to see Adventure get a mention, but no, the Atari version was a graphics game that really shared nothing besides the name with the Crowther/Woods text originial.
I see that Metafilter credited Memepool.
Inspiration is one thing… but I wouldn’t use the word “map”, just as I wouldn’t “based on” (as the quoted passage did), lest people think that the Crowther/Woods game had a castle with a gate, etc.
It was definitely what we would now call a generic, lowercased “adventure game,” and because it was set in a fantasy world, similar elements made their appearance, but the simulated space and the gameplay were very different.
Well, Warren Robinett (sp?) was inspired by ADVENT to make the Atari version — it was basically an attempt to map the Crowther game into something that could play on the 2600. So I think maybe it shared *something* with the text version. :-)
