Decisions, decisions. So let's go for the low-hanging fruit... American Girls.
I confess to having a closet stacked with storage boxes of these dolls and their accessories (saving them for the grandkids, you know). My daughters found many hours of amusement playing with these lovely things, even into their adolescence, when they descended into mockery and condescension, which reached its ultimate expression in the creation of a monumental movie, appropriately entitled "The Tragedy," which starred their brace of dolls, a trio of the dolls' dogs, and the nefarious "Betty Loo," who was a doll of a doll (yes, a doll owned and played with by a doll). Don't ask - it's complicated.
