I played this game all the time when I was a kid.  It was one of me and my sister's favorites, so I got it for my daughters.  It is a very simple game so that even my almost-3-year-old can grasp the concept pretty well.  It also teaches numbers, taking turns, and that there are consequences for your actions.  If your game piece lands on a picture of you doing something bad, you get punished by going back toward the beginning, and if you land on a good deed, you go up toward the end.  This is a great game for all ages, and the younger children have just as much chance of winning as anyone else, which is a plus.
