Can you conceptualize what you mean by real mystery? Do you mean that there is no set correct answer (ie randomization of suspects), or there is a need for real congnitive concideration in solving a crime? or some thing more esoteric?

Oh! so you mean like Zombie Society - Dead Detective by Lu Muja? I like the idea, but also in that game is proper evidence collection and brainstorming a conclusion. I was expecting that to be the kicker of your game, but I understand and see how multiple endings could be a part of a real mystery.
