My sole purpose in posting this was to help EzekielRaiden better understand how the "declare a story detail" mechanic that they tried to grok works in Fate. There was no value judgment about D&D, Fate, or any other game contained therein. There was no value judgment about agency in any game. I was simply explaining the mechanic.
Sorry if it wasn't clear, I wasn't criticizing. Just adding on my thoughts related to topics of conversation in this thread.
