How Does Blockading Work?

[dragof2]

I am pretty sure I understand the basic idea from the tooltip (blocks access to blockaded sea tiles and trade routes can't go through the area), but in practice it doesn't seem to work exactly like that. I'm playing China and doing some fighting with Japan and have blockaded them. But based on my espionage in their cities while I am blocking those tiles, I am not blocking their trade routes or their overseas resources. I have blockaded every one of their cities, but it doesn't seem to matter. Is there anything I'm missing/was changed in the mod about how blockades work? Do I need to have every one of their coastal tiles blockaded?

Did you press blockade button?

Can you post a screenshot of the blockaded area? I believe that if any city is not blockaded, then it will be able to connect everything to the other cities.

I did do some more playing with it, and I think I might have some of it figured out. These two are shots of the initial non-trade blocking blockades. It has every city, but it is missing a spot of coastal territory southeast of Kyoto. (Even after a turn has passed, they still have Oil)

After I closed the gap and had every single coastal tile with a connection to their cities blockaded, then it worked. They no longer have oil, and can no longer build submarines.

I am reasonably sure this is not the case in base civ iv, but it seems like successful blockades require every coastal tile connected to the desired blockaded city to also be blocked in the mod.

Nope, no difference between BtS and DoC.

I mean, that's how blockades work IRL

Ah, I will fully admit, I don't play the base game. Only needing to blockade the cities was the way I saw it described when I was looking around. Very good to know, sorry for the assumption.

It is good to know. I thought the same as you, that you only need to blockade the city tiles. Thanks for the post!

The blockade will deprive access to the coastal tiles from the city. For trade, think of every tile as potentially trade connected: land tiles are trade connected by routes or rivers, sea tiles are trade connected with the respective techs that unlock trade on them, cities and forts connect land and sea tiles. As long as there is any connection from city A to city B, even if it goes first via land to city C, there is a trade connection. Does it make sense for sea trade routes to work like that? I don't think so, but the game does not strictly differentiate between land and sea trade routes. It only finds if there is any connection and then determines if the other city is overseas or not.
