I took a punt on this one because I loved the art style and the description, and it wasn't too expensive. I'm really pleased I did, because it's very fun and not too similar to many other games out there (that I'm aware of). I'm a big board-game player, and it's nice to see something with a bit of a different direction.
Personally, I would be tempted to give this more than 4 stars, but a couple of things hold me back. One is that I think my gaming group is perfect for this game, whereas for some other groups it might not fit quite so well. Our group is competitive without being in-your-face about it, meaning that when I was losing horribly at this game I was still enjoying it, but when I was winning I still had bragging rights. If your group is VERY competitive, it might be off-putting to the loser (and in my experience there has always been someone who never really gets going and ends up with half the score of everyone else). Alternatively, if your group isn't at all competitive, or isn't good at bluffing, it might be an uneventful game.
Secondly, I've only played this three times so far, and would definitely play it some more, but I imagine it gets a bit samey after a while. That might end up not being the case, but it feels that way at the moment.
Anyway, relatively minor complaints. Overall a very good game that I'm pleased I took a chance on.
