In Notre Dame, players play as well-off Parisians in the 15th century who wish to improve the importance and appearance of the city quarter around the famous Notre Dame cathedral. The primary game concept is original but simple card play which players use to permanently improve their influence in the quarter. However, turn after turn, round after round, players must make choices that can have major implications. Because if one does one thing, then the other can't be done any more. Concentrating on one aspect means automatically ignoring another.
