In Dom1 the way "resource sucking" by castles work is sometimes a pain : taking an enemy castle can suck dry out of resources one of your border provinces, where you can no longer build anything ...(if the provinces had sages or was Amazon, it's a bad news
)
I understand the principle, that castles are hub for resources so a % of resources of nearby provinces is sent , but there can be no justification that resources be drained if the ruler doesn't want it and would rather want to build local units !
A nifty feature would be to be able either to
A/ change the resource-sucking % of a castle in a given province, from 0 to the castle Admin % (so the neighbours will keep more of them), or
B/ to be able to establish "trade routes" : these would be "persistent" features, where at the cost of some gold and resource (proportionate with the shipment), you could send each turn a given amount of resources from province A to neighbouring province B .
B is maybe more costly and more "micromanagement" than A, but address more effectively the issue, and I don't think it'll be useful for more than say a half-dozen of provinces, that have neat special units. The rest of the time the "home" units buidable in castles will be preferred.
Well, what do you think of this ?
