(If we are right, could you guide us where to find it?)
Moves got my attention for their capacity to push system elements in the background without weakening it.
Moves are triggered in fiction, therefore they start in narrative and they have already interpreted outcomes, which means that they end in fiction as dynamic narrative input and not as static outcome which needs to be interpreted before narration continues. Using moves seems to create continuous narrative flow of the game like in freeform (game without system), but with robust system in background.
This gives them several limitation so they can not be used for many types of game, but it is very interesting attribute of that mechanic which seems to be really strong in games which doesn't posses those limitations.
