I think, in the oft-cited examples from BW, that roleplaying would be impossible without the resolutions (We found the tower; I found my brother). I think that in any system that boils down to "The GM Decides" where the GM is convinced/persuaded by roleplaying (along the lines of what I understand
@pemerton to mean my "free narration") that the resolution is directly derived from the roleplaying. I think that in any system or instance where the odds of resolution are affected by what has been roleplayed, roleplaying and resolution are intertwined.
