This came up in our first play, and maybe were making too many comparisons to Civilization (the PC game).
I noticed there are a few wonders and leaders that have duplicate cards in the decks (ie Joan of Arc, St. Peters). Is it possible for multiple players to have the same leader or same Wonder built? I could not find any clarification in the rules about this.
Just seems thematically incorrect to have this situation come up but I guess as far as gameplay is concerned it's not that big of a deal.
Definitelly not. There is exactly one of each Wonder and Leader card.
Civil Deck A should contain 20 cards.
Civil Decks I, II, III should contain 55 cards.
Military Deck A should contain 10 cards.
Military Deck I, II should contain 50 cards.
Military Deck III should contain 45 cards.
Along with starting player card and starting cards the game should contain 365 cards.
