I am a bit surprised that boardgamegeek rates it so low. Amazon has 70 5-star reviews, 1 4-star review, and NO reviews lower than that. That's a pretty outstanding breakdown for a game..
it shouldn't be to surprising as you have to make some adjustments to games when looking at ratings on boardgamegeek unless you adore euro worker placement games as those are about the only games that the community remotely rates properly.
If you answer yes and don't mind that you did;
is the game made somewhere then europe? add one point to the average score.
does the game use a mechanic of chance? add a half of a point to the average score.
does it take 30 minutes or less to play? add a half of a point to the score.
does it take less than 30 minutes to learn(by reading the included instructions, not from someone who knows how to play)? add a half of a point to the score.
granted these aren't hard rules especially when it comes to the chance one but it is typically what I do when I look at the ratings as they are pretty steadily off towards my views due to those factors, as board game geek seems to dislike things not made in europe, that use chance as a mechanic or that are quick and easy to play.
