Is Mining inc better with 2 iron rather than 1 iron (or gold, silver, etc) ?

[guermantes]

I have founded my first corporation, Mining Inc. I have or am trading for all five resources. But I notice that even though I have all five, iron has begun to come up as being offered by the AI in trade. So I traded for a second iron hoping to see some benefit, but I can't see any. Is it useless collect lots of the same resources when using corps?

I could be wrong, but I thought it was +.75 hammers per source.

 

[guermantes]

To me it seems to be 1 hammer per source type. Weird, since the computer won't offer me e.g. spices if I already have them, but now it offered me a second iron, and then even a third iron. Why?

 

[petersc]

Are you running State Property by any chance. Corporations have no affect if you are using it.

 

[guermantes]

No, I'm running free market. I just don't see see any effects from the second source of iron I have acquired.

I see other effects, so it's not that Mining Inc is completely off. A one hammer city now has 6 hammers Base production since I have all five resources. But I thought I would get yet another hammer in incorporated cities when I acquired more iron.

Might be a rounding thing.

I believe this is correct, and to answer the main question: yes, acquiring moresources of iron boosts your yield from mining inc. The idea is to amass all the iron/copper/gold/silver on the map and then your mining inc should yield >15 per turn per city. As far as not seeing the bonus sometimes and seeing it other times... that does have to do with rounding. Civ IV always rounds down as a rule of thumb so 1.50 bonus hammers from mining should only show up as 1 extra hammer. Try adding one more source of metal and you'll probably see a difference in the yield.

Like others already got this, looks like rounding thing Sometimes its good, as 2 Floodplain tiles inside BFC won't make city unhealthy

On standard settings, Mining Inc gives +1 per resource. Duplicates count in that calculation.

The yield scales with map size, with larger maps giving less per resource consumed.

Not per type, per each instance of ANY of the resources controlled by that corp. Example: you are running Sushi on a large water map, you can buy up all the excess Seafood resources and get a massive food boost in any city using Sushi.

The fact the AIs are selling you resources that are surplus (surplus to you, not them; it goes without saying unless they are a vassal the AI only trades its surplus resources anyway) means that you can use it to improve your corporation yield. So you can buy as many extra Coal, Copper, Iron, Gold or Silver as they have extra of and each one will improve the hammer boost of Mining Inc by +1. At least until they found their own corp that competes and then they will refuse to.
