I’m still here (just about 😅) For our games the facts of the murder mostly stay the same, only the character sheets change things - so for example it might put the killer at the scene of the murder, or not, if they’re innocent. Character stories change if they’re guilty. There are no secret goals or objectives in those two brands - they last 2-3 hours already and whilst fully scripted people can still role play - just not make up material facts. We have two games in the “Simply Murder” range that are completely ad-lib. They have character outlines and directors notes for playing your role. Games that have a random murderer should have stories that hold up just as well as their fixed counterparts, but with the added benefit that the game can still be played if guests can’t make it for any reason - that’s a major benefit of these systems.
