I'm not used to seeing the words "ancient" and "hard-core" together, but thanks for sharing the video!
It's crazy how much money a designer could make off a single game back then. Annual salary plus commission from GROSS sales? Modern publishers would laugh. From the documentary, it seems that the designer of Atlantis made over a hundred thousand dollars off it (a few month's work) and had the stock gone public, would've been worth about $12 million. You can live on that, especially during the 80's.
