This is great! I’ve always felt that Star Wars was more fantasy then science fiction. I was not aware that the early draft leaned more toward hard sci-fi and, though I have long been aware of Campbell’s influence on Lucas, I had no idea that his ideas were so pivotal in moving the concept in a more surrealist direction.

It’s quite fascinating to see just how much Lucas’ ideas change from draft to draft.
There was also a comic adaptation of the 1st draft made in 2013:
