Political groups can agree on trade through diplomacy. A trade agreement between two factions This is just another symptom of the larger problem called “Total War Diplomacy”, something that has been shown very little love and attention since CA was first born. They even took poor little diplomatic boats and cars on the campaign map. They waved their finger against diplomacy and also took trade routes. Tilea and Estalia are also very difficult to obtain as business partners for reasons I can`t understand. On the left (on your side), the interface shows you how much you earn with the trade and resources you export to your trading partner. The right side shows how much money they earn and what resources you import from them. You can only negotiate with other groups if you have produced at least one commercial resource (iron, stone, wood, etc.) in one of your colonies and the fraction with which you want to trade does not yet have it. The value of each resource is different (you can check it in the bottom left corner of the diplomacy screen). In addition, the amount of gold you earn through trade depends on the amount of resource you can produce (the higher the level of the building it can manufacture, the more gold you will earn with that). Note: The Tomb Kings are the only faction that actually uses resources for their mortuary cult mechanics (Edit: a similar mechanic called forgery has been added to the dwarves in Warhammer 2 only since this response was originally published). For all other groups, resources only increase the value of trade agreements. So you`re generally right to think that these resources are not actually used by the trading partner, but not in this particular example.
It also depends on the characteristics of the political groups. A group like Kislev, which has passive quality, is by no means to act. It works in a rather strange way. By signing a trade agreement, you send all your resources to the group you are acting with (except those the group already has) and vice versa. A simple example allows you to better understand: in-game diplomacy may not be as important as in other games of this genre, but it`s still a pretty important aspect of the gameplay. With this, you will be able to trade with other factions, maintain friendly relations (or sign military contracts) or even assimilate other factions to your kingdom. I have never seen evidence that more commercial resources would increase the likelihood of someone agreeing to a trade agreement. The diplomatic system is very veiled here.
I have seen that groups with 200-plus relationships are opposed to profitable trade for them and that groups with 5-strong relationships accept the same trade. By clicking on a political group, you can see different information, such as. B, all contracts between your groups or the commercial assets available to this group. If you show the mouse on a group, you can see the list of things that have a positive and negative impact on your relationships. Information on this screen are divided into: Beastmen, Greenskin and Warriors of Chaos fractions cannot act. Each resource you export increases your group`s income, while each imported one increases your trading partner`s income. Unfortunately, you can`t decide what resources you want to send them and what resources you want to receive.
