Concordia: Mare Nostrum is an expansion for Concordia released in 2026 for 2–5 players, 60–90 minutes per game, and ages 13 and up. It was designed by Mac Gerdts and its main mechanics are Area Movement, Market, and Deck Construction.
A Concordia expansion map where you colonize Roman cities only from the sea. It does completely away with routes between cities. While the ships share sea regions from where they can build new houses in harbor cities of the Roman Empire, the land units offer additional new strategic choices inside a separate area on the board. It is a double sided board, designed for either 2 to 4 or for 3 to 5 players. You win by appeasing the Roman Gods in the usual manner of Concordia. —description from the publisher
Concordia: Mare Nostrum supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Concordia: Mare Nostrum is 60–90 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Concordia: Mare Nostrum for ages 13 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
