Because we can do that and care about setting considerations! These things are not in conflict.
The setting wasn't considered using the encounter building meta-tool. This is weird, it's like you want to only look at the parts that meet your endpoint, and refuse to look at the start of the chain. Why is this encounter here? In the example, it wasn't to fulfill a setting need, it was designed to create a challenge to the PCs, using the metatools that enable fair encounter design. You want it to be about the post-hoc rationalizations, and that's fair, I guess, it wins your point, but it's ignoring that you're arguing for post-hoc rationalizations.
I changed nothing. You said that the reinforcements are in the next room and ready to come to help.
No, I said that the reinforcements were there because they filled out the encounter budget -- not that they fulfilled any setting function or need. You've added that.
Your claim was that if we care about high concept simulationism, we save the PCs. And I said that completely depends on the high concept we are simulating. I did not change the example.
You did change the example. My example does show care about high concept simulationism. Yours would as well. There's not one and only one way -- but there was the example I gave and then the one you changed to make your point.
Look, I crafted my example with care and intent. I know what I said, and why. You led your objection with a "but" and then changed one of the things I was careful to be clear about. So, yes, you changed the example, and this protestation is just very weird.
The idea of the character. Some people don't want their character to die even if it was the last session and the story wouldn't continue anyway. Trying to force this to be about story is just you trying to shoehorn things to conform into your model. It doesn't work.
The... idea of character? Help me here, I don't follow this jargon (is it jargon?). What does this mean, can you explain what the idea of character is? When I try to, I end of thinking of things like "what this character has done, who their friends and goals are, and the idea that they'll continue to do cool things in the setting even if I don't play them." We all like happy endings, right? But all of that is reliant on story and setting, yes?
How you feel that's going? Have you considered that the reason people 'are not getting it' is actually the serious flaws in the theory?
No. Because the parts their pointing out are often just misunderstandings about what the theory says. That's not a flaw in the theory. Perhaps it's a flaw in the accessibility of the theory. You can have that criticism for free as well.
