Ralph Mazza, your example is exactly one of the things that I am really wresting with.  I’m making a Cthulhu PbtA and the investigation moves HAVE TO WORK BETTER than I have ever seen them work before.  I have always felt a gear grind when those kinds of moves happen because people struggle with asking what they want to ask through the filter of the questions presented with the move.  I thought about just making it completely open ended and being done with it.
