I received this as a gift for Christmas. I'll start by saying the game itself is interesting and fun -- if you can actually get enough people together to play. You have to have at least 5 people. Also, you hardly get anything for the amount of money you spend -- you get a tiny box, and the only contents are a stack of cards and one fold-out page of instructions.
The cards only serve to let players know what role they play (villager, cult member, seer, etc.) You could easily just write the roles on pieces of paper. The rules are incredibly simple (they fit on a single small piece of paper), so that gameplay is very limited.
Honestly, I wouldn't recommend this to anyone. It feels more like the kind of game you can find directions for free online. Again, this isn't really a board game, and it isn't really card game, as the cards don't really serve any purpose once you are assigned your role. If you pay $20 for this, you're going to be disappointed when you open the box...
