Rome was not built in a day, but Ostia: Mariner Edition gives you about two hours to build a fleet, cross the Mediterranean, and prove your shipping empire deserves the Emperor’s attention.
Set in 103 AD, this strategy game places one to four players in the sandals of competing Roman merchants. Every ship you build can produce resources, unlock an action, carry goods, or push your growing operation farther across the sea.
Ostia begins at the Roman port that connected an empire to the wider Mediterranean.
Players gather wood, stone, coins, and permits to construct ships, establish outposts, fulfill imperial orders, and expand along trade routes. Each move can strengthen your merchant network, but every resource committed to one goal is a resource unavailable for the next opportunity.
The result is a game about building an efficient commercial engine while watching rival fleets reach ports, claim discoveries, and secure valuable opportunities before you.
Ostia’s cleverest idea is its mancala-inspired action system.
Your personal harbor is divided into six sections, each associated with a resource and action. On your turn, you choose one section containing ships and distribute those ships clockwise around your board. The section where the final ship lands determines which action you may take.
That means every decision shapes more than the current turn. A move that produces exactly what you need could leave your ships poorly positioned for what comes next. Meanwhile, an action that looks modest now may set up an efficient sequence across several turns.
There are no wasted calculations here. Your ships are your workforce, your fleet, and the machinery driving your entire strategy.
Before moving any ships, count where the final one will land. Producing the right resource is helpful, but activating the right action is what turns those supplies into progress.
Keep your long-term scoring goals in mind as your operation grows. Ships, buildings, completed orders, and other accomplishments can become more valuable when paired with the right bonuses, so an empire with a clear direction may outperform one chasing every available opportunity.
Watch the trade routes as closely as your personal harbor. Discoveries and destinations reward merchants who move decisively, but sending a ship across the sea without the resources to capitalize on the journey can leave it waiting while your rivals pull ahead.
Above all, think several turns forward. The best move is often the one that leaves your harbor ready to produce, build, and sail again.
