Can someone explain exactly what is meant by a corporation "consuming a resource"?
Once a branch of a corporation is built, does that branch actually remove that resource from the trade network? Do multiple branches of a corporation remove multiple copies of a resource? Can you starve a civilization out of its resources by "consuming" them with multiple branches of a corp?
Or, are resources only a prerequisite for building a corporation branch? Meaning that a corp branch can only be built if the city has access to the required resources, but building the branch has no impact on the availability of that resource to the rest of that civ's trade network?
If the latter is true, then it would still mean that multiple copies of a resource are irrelevant, since the first copy can feed an unlimited number of corporate branches, anywhere in the civ.
Can anyone who's played BtS explain how this actually works?
No, CORPORATIONS DO NOT REMOVE THE RESOURCES FROM YOUR RESOURCE POOL. I dont think the required resources are even a prerequisite for building the corporation, all you need is the required great person and tech. It is true that you would be able to spread the corporation to all of your cities, but it costs money to spread corps and you have to pay a maintenance fee so you better make sure that the city you are spreading the corp in has a courthouse and the city with the HQ has a grocer, market, bank, and wall street
