In the years since this game has been released, has anyone been able to figure out how the economy works?
--- For naval trade, I thought alliances were important and possibly even neutrals can have their trade blocked in a war but now I am unsure. Generally each new ship pays more then itself but I have had my economy get worse with increased trade several times. It can go from 1000L excess to -1000L in a single turn with no apparent changes (ie, concerning my kingdom directly).
--- Does adding port actually do anything if one has no navy yet?
--- In the Med, it seems that if one completes a circle, ie, a trade link that connects to itself, the economy suddenly gets a lot better.
--- Economies in general seem to shift a lot and quickly?
--- Does an inquisition affect your economy significantly?
--- Does simply losing favor with the Pope (no sanctions or anything, noted by an uptick in assassins, etc) cause the economy to lower (it seems to)?
I do mostly understand the more or less obvious things like distance from king, poor farmers, natural disasters, lord character flaws, etc but there is obviously much more and what may be a large dose of randomness.
