My daughter and I just got done with our first game, and had a blast. She is very smart for her age, and I was a little easy on her since she was the lone investigator in the mansion. I'm sure we may have missed a few things with the rules, but that will be ironed out in the next few games or so easily, as we both get a much better understanding of everything.
The best part of everything was that the game literally came down to the very last turn, and roll of the dice as to whom would win. The game did take a little long to complete (close to 3hrs), but there was a lot of looking over the rules again to make sure we were doing things correctly. I have to say that I haven't had this much fun playing a boardgame with my daughter in a long time. The tension in the air with the last few turns set the tone perfectly, and made it that much more enjoyable. We are already looking forward to our next game session soon. It's safe to say that this game is already a big hit in the household.
