This is a fun idea with cute art. For the English translation of the game, the card ranks should be K (for king) instead of R, Q (for queen) instead of D, J (for jack) instead of V, and A (for ace) instead of 1. I would have liked to have had an A4 option for the full color version of the cards instead of having to choose between full color individual images or black & white A4 pages. Also, it would be fun if you included an A4 page of cards with blanks where the numbers, words, and images should go, for people to add their own cards to the game if they wanted to throw in some more of their favorite Douglas Adams references or even expand the set to a full 52-card deck if they were feeling ambitious.
