Who has the final say has not been in question.
No?
What has been argued is that the DM should not overrule a power unless absolutely necessary.
Who decides what is "absolutely necessary"?
"The argument that a snake being knocking prone is UNreasonable has been soundly, objectively defeated" only if you accept the evidence given. And, if you accepted the conclusion before the evidence......Well. Of course you conclude that it is soundly, objectively defeated.
And, again (so that we don't lose track), I accept that, under some circumstances, a snake
can be knocked prone.
But
far more importantly, IMHO, I accept that the GM may rule otherwise. And I don't require that the GM prove it is "absolutely" necessary, either. Just that the GM believes that it is the best call, to make the best game, at that moment. That's all.
Accepting that is part of being a good player, IMHO and IME....a
major part. I don't expect a "gamer utopia", but neither do I believe that GMing is "a big, largely thankless, job and bears most of the burden for making a good game that is engaging to 3-5+ completely different personalities". I have certainly been thanked. I've been thanked a lot over the years. I've had former players from over 20 years ago look me up through the Internet to thank me....to tell me that they are continuing campaign milieus I created.....and to ask me for advice.
Nor do I believe that "If something has to give, it's almost always going to fall on the DM. And should."
I run games I enjoy running. I run games that I would enjoy playing in.
If you don't want to play in the games I'm running, that's fine. I have
always had more people looking to get in than I have at the table anyway, and I can do something else with you that we both enjoy. That's worked for me now for over 30 years, and to this day I could still get 15 new players for the weekend if everyone dropped out right now.
FWIW, I think my system works fine. I run the best game I can, and that requires running a game I enjoy, in a manner that I enjoy, with people whose company I enjoy, and who also enjoy the game as it is run. There is no shortage of such people, so it's winning all around IME.
YMMV, though.
