Castles and resources question
 

I have built a castle next to the enemy capital, with castle. Do I steal a portion of his resources and he a portion of mine or do we get nothing from each other?

Why would I do such an odd thing? He has a large army of high strength units that make it next to impossible to break down the defenses and a third nation keeps attacking me when I lay siege. I decided to let the third nation carry the pointless siege, but wanted to keep the other nation bottled up. I am also attacking their dominion while I pull together a much better siege army. This is SP, which explains some of the odd behavior.

Anyway, am I reducing their resources or just sharing them?

Neither. You are just denying him the resources from the province with your castle. Castle drain resources from neighboring provinces only if that neighboring province does not have a castle. They cannot drain from each other.

Good! His high resource units are tough to kill, while his low resource units melt like ice cream in the sun. The province I built the castle in is a cave province with high resources, so I am pleased to deny it to him. Now I just need the weekend to play!

I'd be a bit surprised if castles were drawing resources from provinces owned by anybody else.

Re: ?
 

You are correct - they do not.

Like they said -- castles do not get resources from provinces that are owned by other players... your castle gets the resources from your properties, and his from his.

I'm still not sure what your castle is doing for you, though -- providing you supplies? A safe place to hide while his army sieges you? A place to recruit forces?

The castle ended up being a place to hide and stop them advancing and I almost lost it twice. Once they attacked and I got very, very lucky. The second time I started with a big army, but they starved me and I lost 75% of the army before the relief force arrived. The third seige ended last night and I finally carried the seige over to their castle.

Now, once I capture it, does the division of resources change? That is, if I have two castles next to each other, do the resources get shared in any way?

Castles don't share resources with each other. If they have common neighbours that don't have castles, those provinces might get drained of all or most of their resources, but this will give more resources to both your castles.
