The cover of this game is dangerously close to the innocent family game. We bought it at a "breakfast with santa" event, never considering there was a adult-only version. Pretty surprising for the grown ups and eye-opening for the kids! The only hint on the box (after we looked closer) was it said it was for "4 or more adults". Shame on the manufacturers - there should be a better "heads-up" warning. From the other reviews, it looks like we weren't the only ones caught off guard.
