Innovation: Echoes of the Past is an expansion for Carl Chudyk's Innovation, released in 2010, that mirrors the construction of the earlier game as both include 110 cards, 105 cards that are divided into different decks (labeled age 1 to age 10) and five cards that show special achievements that can be claimed. The expansion's 110 cards are all new.
In loose terms, Innovation is a Civilization-style game in which players first have access to low-powered cards in age 1, then build up to more powerful cards in later ages, stacking new acquisitions on old to build the strength of their holdings. Players meld cards, score points and take special actions (called "dogma actions") unique to their cards in play in order to claim achievements. The first player to claim 4-6 achievements, depending on the number of players, wins the game
