If this game looks even the slightest bit interesting to you, pick it up - there's far more to it than meets the eye. It's not quite a board game, not quite a deduction game, not quite a storytelling RPG.. instead it's a crazy mix of all of those put together.
The rules are actually incredibly simple - everyone has the same list of basic actions, and no weapon is more powerful than any other. But the more you play, the more you see the deeper strategy behind everything. Your Secret card gives you special moves, yes, but it also influences your character's personality and relationship to others.. but it ALSO is something you want to keep hidden at first, because if someone else guesses your card, they get a bonus.
Which means that there's a Clue-like vibe to the game, where the cards that have been revealed provide a hint to what cards your opponents may be hiding..
And on top of EVERYTHING else is the superb roleplaying aspect, where you're encouraged to embrace the dark humor, bad puns, and the flamboyant, larger-than-life personalities of the genre.
OH, and did I mention that even after your character dies you influence the game as a ghost, wandering the mansion and spooking others.. and perhaps more?
AND the game even comes with suggestions on how to hack it into other settings, with multiple "Deceased playbooks" that describe different locations to kill and be killed in, some with special, interesting rules!
It's like the silliness and dark humor of the Clue movie with the secrets of Knifes Out meshed with the grandiosity of Vincent Price. It's absolutely amazing and I highly recommend it!
