My favorite board game. It refreshes the memory or informs us of ignored facts. The only thing I blame him, as for all games of this series is not to be accompanied by a book that would explain the answers (that's right, it would have to be big!). Also, sometimes, it remains unsatisfied. We should play together and deepen the answers on the internet or an encyclopaedia but it would slow part of the game. But never mind, I still like!
