Two things really make this a 5-star game for me.
First, the game is easy to learn. Most of the games I have played were with my wife's younger brother and sister (ages 11 and 14). They picked up on the rules quickly and enjoyed playing with me--they can always count on their 'big brother' to bring over games they like.
Second, despite what the box says, the game only takes us about 20-30 minutes to play, if even that long. And that is a big bonus, because most of the time, there isn't time. Being busy families, it is rare that either family has time to break open the games that take hours to complete.
This is a great way to entertain when you don't have all day.
