As some one who started in the Three little book days.
Original 70's DnD started as players vs a killer dungeon built by the DM Aka Gary Gygax
Ironically it was those of us who crossed over from traditional wargames who where more into the role playing your character.
You can see more recent players in pathfinder and dnd 5th wanting to win "the game", the full on RP style of the Mighty Nine of The Glass Cannon is quite different are actors or semi pro ones AND THEY ARE SO WELL BEHAVED""
To be a dungeon master is effectively to achieve AGI. It’s... not realistic. Current NLP systems have mapped out what language means, and can use that to generate text. But they have no idea what the text means. It requires incredible knowledge about how the world works and an ability to explain its reasoning in plain terms.
