I do often keep things general. If I need to narrow something down to a single game, I'll mention it by name.
This is just a pure dodge of the actual question. Name a game--any game, any
single game--that actually works the way you described. That's all I ask for--the name, not even an excerpt from the text showing the truth of it. I'll actually do the research and track this down.
Until then? You are literally inventing boogeymen to scare others without having a scrap of evidence that they actually
exist. I won't just take your word for it.
I'm not sure there is an answer to that....It's a Matrix type thing. If you are hopelessly in the Matrix, then you willingly follow all the rules. If your not part of the Matrix things are different.
Ah, so it's a totally ineffable thing that cannot be spoken of or shared, but makes you strictly better than anyone who doesn't understand it? Wow. This has gone well past ridiculous and into parody. Do you expect anyone to take you seriously when you pass such heavy-handed judgment on anyone who disagrees with you, and then when someone actually tries to understand, you say, "You're incapable of understanding."? For real?
If I didn't know better, I would genuinely think you were pulling my leg.
So your looking for a game rule that says you don't have to follow the game rules?
A rule, an advice passage, a discussion. Anything
in the text itself which talks about it in the way you described. Which, for the record, was as follows: "In the vast majority of game the DM just does what they want, on a whim. And you want and need a good DM to have a good game."
I know, from past experience, that you're
very sincere and intentional about the use of "on a whim." You very specifically do in fact mean the DM doing LITERALLY whatever they want, whenever they want, for as long as they want, with absolutely no considerations, limits, restraints, or anything else. If they feel like snapping their DMG shut and saying, "Rocks fall, everyone dies" then you would be 110% supporting them.
So: Where do the books tell us that DMs should behave that way? Where do they describe DMs acting "on a whim" whenever, wherever, however frequently?
