The cards are indeed great. They help simulate some of the real unpredictabilities that occurred during the actual war. Additionally, they have a balancing effect, if there is a weaker player playing against a stronger one. They add so much to the game, it is almost like buying a whole new game. Personally, I did not want to purchase one of the newer games (Europe or Pacific) because I like to simulate the war in its entirety (rather than just a segment) and these cards are the perfect way to do it. It adds things to the game like spy capibilities, negociations with neutral countries, and many welcome enhancements to your ground, air, and sea forces. All in all, it forces players to rethink their strategy again and again, and makes each game new and exciting, rather than using the same old strategies again and again to win. The accessories available are great also, as they add greatly to the visual effect of the game. The sight is definatly worth checking out!!
