My wife and I rented this because we love the television show. If that's why you are renting this, you will be disappointed. The game only lets you create one avatar, not an entire family - at least in single player. (We couldn't even get the party mode to work! The game wouldn't recognize more than one controller.) Some of the questions seemed like rejects that the tv show couldn't use. One question was "What age is a girl when she first puts on lipstick?" so the answers were "8,12,13,14,15,16,17"... it didn't require any thought - you just guessed the next number.
Also, there is no John O'hurley. The host is a faceless voice. There is no banter either, you just jump from question to question. I think that most of the charm of the tv show has to do with the actual people involved, and this just falls short.
