If I've surrendered authority then I no longer have it - aka lacking that authority.
I'll take your word for it.
I'm just glad we are on the same page - that DM authority can easily be more limited than typically envisioned in these discussions.
Which going back to my original point - in my game a player was able to accomplish moving the game forward when I as the DM could not. So now that it sounds like you agree with this assessment - how does this not make the case that a player can at least for some sessions be more important than a DM?
When I talk about GMs having greater authority than players, I am talking about a typical GM in a typical game, rather than FrogReaver the GM in FrogReaver's game. We can make generalized statements about GMs as a whole. Those statements may or may not apply to a particular GM, such as yourself.
You could play 5e with something like Mythic GM Emulator, eliminating the role of GM as being distinct from that of a player. It wouldn't really be pertinent to this discussion though.
Same thing here. You voluntarily entered into a contract that limited your authority as GM. It tells us something about your game, but we can't generalize it into telling us about GMs in general, since that is not typical. The most we can say about this is that a player at your table can have more authority than you (specifically, FrogReaver). A square is a rectangle, but a rectangle is not a square.
Like I've said before, I've largely tried to avoid using the term important in this thread because it is very subjective. Important in what sense?
A king is more important than other people in the sense that the king has the greatest governmental authority (yeah, that may not ALWAYS be true but for simplicity's sake let's just assume it is).
However, many would say that the king exists to serve the people, and derives his power from the people. So in that sense the people are more important.
And, arguably, from certain moral standpoints the king is a person just like any other citizen and therefore his happiness is no more or less important than that of any other citizen. So the king is of equal importance to the citizens.
See what I did there? I just showed that a king can be of greater importance, lesser importance, and equal importance to his citizens. Which I think says a lot more about the subjective nature of the term important than it does about the relationship between kings and their citizens. (Also, no, I am not equating the role of GM to that of a king. I'm just showing how subjective the term important is, that's all.)
My standpoint has been that the GM is equal to the players in the sense that everyone's fun is equally important. However, GMs have both greater authority and responsibilities than a player does.
