The entire point of the historical scramble in the exploration age for resources like spices and gold, as the game tries to mimic, was because those resources were not available or scarce in the homeland, and their people paid a pretty penny to have access to resources they had to sour the globe to find.
I don’t understand the logic behind the recent changes to resources. Horses shouldn’t be a treasure resource if I have a bunch of horses all over my home continent. Why would I focus all my energy in an age to bring in a resource I already have in spades, when there are plenty others I don’t have yet? Your medieval citizens aren’t going to pay top dollar for something they have at home just because it happens to be across the ocean, and it’s not going to financially be worth trying as hard as the game makes you try for these resources without the scarcity being priced in. The only exception I could see is silver/gold.
Why are my citizens all 😍 for horses from an across the sea but 😕 for the ones right beside them? It’s ahistorical to have the system work this way. The treasure resources themselves also spawn too infrequently now. There are a million bugs with the game, why are you prioritizing changing the few mechanics that worked?
Everyones got there headcanon its all good
