"Games are usually either boring and instructive or violent and fun. This one is lots of fun (hence kids flocking around the table the whole time!!!) and you learn cool stuff."

"As I was putting Carolina to bed she was telling me how much she loved the game and she was so bummed that she would have to wait so long to buy it...ha ha, it was a hit!"
