REQUIRES BASE GAME
Innovation: Echoes of the Past changes game play from the base game in a number of ways. First, the number of cards in each age deck is determined by the number of players, instead of being constant. Second, to create the age decks, players shuffle together the cards from the base game and expansion for each age, then deal out the proper number of cards. Third, the maximum player count is increased to five.
Fourth, and most interestingly, Innovation: Echoes of the Past introduces new game mechanisms. With foreshadow, a player can stash a card under his player board, then bring it into play (and use it) on a later turn when he melds a card that's from the same age or a higher one. With echo, when a player takes the dogma action of a card in play, he can receive additional actions showing on that card and any other cards visible in the same stack.
