And as I mentioned before, another idea is to flesh out the stories even more, so that it could be expanded into a mystery game, or an adventure game, or an escape-the-room game, where in order to continue you need to talk to people, and some of these people will give inaccurate information, because they didn’t notice a flaw in their own reasoning, and you will need to point out the flaw in their reasoning before they will give you the accurate information.
Many of the possible responses would be to question why the person believes specific things that they just said.
Well that would be an interesting game mechanic.
How about a courtroom drama?
I object!
