The whole concept of being able to go out and fight monsters in you own fantasy campaign like in the books you read was itself a dream which D&D brought to life, so the entire genre really owes it to that.
I also recall hearing as well that a lot of the foes were directly taken from the Monster Manual.
Lastly, I think the story about it being their last game/game to save the company has been largely exaggerated over the years, and that Square really wasn't doing all that bad, at least in comparison to other developers who indeed went on to survive those early famicom/msx days. I know that's not the consensus today, but I'm just saying what I've gathered from reading about it over the years.
