I have played 10,000+ games over last 30 years, and I am surprised that this game does not get attention for families.
If you have a mix of different ages with one being under age of 10, this is a must buy for up to 4 player game play.
The only annoying aspect of the game is if you have less than 4 players a mandatory robot player plays.
If they allowed an option to play only people this game would be perfect.
