Serenissima is the new Ystari edition of the 1996 game (Méditerranée in France). The rules have been updated and the game is more fluid.
In Serenissima players represent a merchant family during the Renaissance. Players attempt to balance the need of trading and open commerce versus the cut-throat economic piracy of the day. Players create a fleet of ships to purchase and move various commodities around the Mediterranean while also keeping well manned ships to attack and defend against other player's fleets.
