This DVD is about as simple as you can get. The announcer gives you 10 questions a round, you each write the answers down on a piece of paper, and at the end of the round, he gives you the correct answers, and you score yourselves points.
So what is here that a book cannot do? The questions are written on the screen as well, which may help people who are hard of hearing. There's sometimes a picture or small video clip (with no sound) to help illustrate the question - illustrate it, mind; the question is never "who is this?" - a lost opportunity there. Also, the same pictures/video clips are used with more than one question.
But that's basically it. You can choose 3 rounds, 6 rounds or 9 rounds - but given you are keeping the score, that's the equivalent of playing a 3-round game once, twice or three times, so why bother with this option? Also, you can choose the level of difficulty of the questions - easy, medium or hard - but I can't have one round of easy, one of medium and one of hard. Well, I could reset the game after the first round, I suppose. But no children's questions; I guess in this pub, children aren't really allowed.
If the DVD wasn't so inexpensive, I would have only rated it two stars, but it's not that dear. Just bear in mind you are getting a glorified quiz book - and not that glorified, to be honest.
