I rated the 2005 version as 1 star, and Volume 3 as 2 stars. Well, Volume 4 is just as Volume 3.
Overall, it is as interactive as a book. And you are forced to play the game in a particular way which is not mirrored in the TV show.
There are 5 rounds:
The second round is to guess the top answer only for 50 points.
The 5th round is the "Big Money" round for both teams, and again is only for top answers.
In the other 3 rounds (for example) Team A notes down their 5 answers. As soon as an answer comes up that you don't have, you get the "wrong" sound, and Team B has a chance to steal. There is no concept of having 3 lives - just one answer you don't have, and that's it.
Also, you have to keep the score (how rubbish is that?). For example, when you try to steal he asks "Team B, did you steal?" However, he is not interested in the answer; your only option is "Next Round".
Overall, still as interactive as a book, and still not fun. Basically, a book of Family Fortunes would be much better than this.
