Yep! I really enjoy Anno 1800 but I took a break right before industrializing. I needed a chance to clear my mind before going back to try out the engineer and investor tiers.
But Anno’s ships are there to support the island supply chains, and don’t really have any logistics mechanics of their own. Transporting goods to the port and onto the ship all happens automatically. (Which is fine; Anno doesn’t need to be more complicated on my account.) The other game I played that came close was Cities Skylines, since it provides all the tools to design port infrastructure and manage the flow of goods in and out.
I think games about maritime logistics, specifically tramp shipping, could be interesting. I’ve really only played games about maritime trade, though: buying the commodity at point A and selling it at point B. That’s different than logistics of actually getting the commodity from A to B.
If you don’t mind a little tangent, let me start with Anno as an example. In Anno, some of your ships will repeatedly run the same route between islands, these are your lines. Others will go wherever you need them for specific trades. These are your tramp ships. They’re called tramps because their uncertain schedule makes servicing and supplying them tricky.
IRL, these ships lose money whenever they aren’t loading, unloading, or moving cargo, so owners try hard to avoid downtime. They try to schedule refueling, provisioning, crew changes, coast guard inspections, you name it during the 2-3 day window they expect to be in port. Everyone in the port knows this and charges accordingly.
And these schedules never work out, so owners constantly have to figure out how to make do or push back operations to the next port.
There are lots of potentially interesting decisions in the nitty gritty. Do you take on a lucrative contract to the U.S., even though you’ll need to schedule downtime for inspections? Do you leave it to your chief engineer to fix an anchor winch or stop for repairs? Do you skimp on potable water so you can leave on schedule? Do you establish or buy local services to save money in key ports?
I’m watching a Let’s Play for TransOcean right now and it seems to focus on these sorts of decisions. But I won’t be able to try it out for a few days yet.
