This is very thought-provoking. Could you make modules and content that can then be run in this mode? Could the GM be automated to remove the element of cheating and ignoring die roles?
A major issue I have with tabletop RPGs is the illusion of danger. You're going to fight all these baddies, but it's all really set up for you to win in the end. People get attached to PCs and then they can't die. PCs slowly become all powerful, and it's just self-indulgent.
I see room in this to play a different kind of game.
