Fun evening playing Clue with my hubby and son (25). My hubby commented on how he liked the traditional game better. That it was easier to follow who was where and how to reason out who was the killer. Interestingly my hubby never enjoyed Scooby-Doo as a child. Thus my assumption is that my son and I enjoyed it because we both enjoyed Scooby-Doo as a children and could relate to the characters and weapons where as my hubby could not. I wonder if they have a Clue game based on John Wayne westerns.

You started with saying your were playing Clue, but you never mentioned it was the Scooby-Do version. I think it would have been interesting to know how old your son is as well. Did you ask him if he learned anything? Who won the game? How much different was the Scooby-Do version from the original version? Its sounds like it inhibited the experience for your husband, but not for you and your son.
