First of all; this game has good graphics. Therefor I don't think it's just a game, but also a bit of a collector's item for fans of Doctor Who. The characters are not only from Series 5, but also the Series 4 Specials. Sadly, David's Doctor is not included. Gladly, the Master is!
The game is something you can play for hours. Sometimes it can manage to bore you; causing you to count the cards in order to have a winner. But I suppose that's a common thing with cardgames anyway.
It's really something you can only play when someone joins you. That can be tricky, especially when none around you likes Doctor Who or is into playing games.
It's easy to play. And because of the graphics is not only just a game, but also some sort of collectors item. With a bit of imagination you and your friends can use them to play other things than just Top Trumps, where me and my friends tried to act like the character in our card on order to be guessed by the others who it was.
