Daunting Diamond Thievery
I went for the pre-made kit with no spoilers. Giving this game a five star review for the characters. We had a group of people, most of whom hadn't done a mystery before and didn't particularly want to be doing one, and without significant props or costumes, they were still able to get into who they were supposed to be and have fun with it. This is supposedly one of the easier mysteries and only one of us got it, not sure if that's on us or on the mystery itself, but we all got a kick out of the fact that each one of us was accused and no one was accused by more than one person. It was like a daisy chain of accusations. It was easy to create atmosphere inexpensively, and while we didn't do any of the after mystery games or search, interspersing the mystery with the meal took us about 4 hours. Special shout-out to the support staff here. I didn't need support once I received the kit, but they were phenomenal at helping me figure out what would work best for my group!
