Or there should be some mechanic to trade (within the country) manpower for industry to represent the imperfect substitution of manpower for machinery that happened in China and India. (...) Also, allowing for some sort of grossly inefficient "MP for Industry" mechanic would make it so that China and the Raj aren't just endless manpower generators since, historically, manpower was a constant problem in both countries.
Would work very well, but would have to be based on some formula on population, not the currently free manpower since the conscription system would mess with that.

So much this, but the amount of threads and posts that want to remove difficult strategic elements of choice makes me scratch my head in disbelief. For example there's a thread at the moment where some guy wants a button to set the exact amount of resources he keeps, so they don't go to waste. Press it and you're done. Fortunately the devs won't take a blind bit of notice of anything which goes against the Meier principle - it's clear from their wishlist and upcoming dlc that they intend to add interesting choices, not remove them.
Games are 100% about choices. If there is no choice there is no game. And the more meaningful of them are there, the better the game. (as long as it manages to make you care about the choices) However, one has to work within the limits of the AI and think about the situation for all nations.
If a nation has less than 8 resources available it essentially will never be able to find an buyer. And the AI will always want to import to avoid the production penalty. This makes it so that most of it's CIC will be wasted. Honestly, trading should be a non-brainer. What should be the choices are: Who to trade from? Are trade convoys defensible? And you still have the metagame where you need to make available an equal portion of all your resources for export and how big that percentage should be.
This may sound like an cop-out, but I would argue that more meaningful interaction between countries, like trading, the better, as if you have no interaction between an country you are kinda meh about them overall.
Only some of what Im saying could be done through CIVs. CIV trading doesnt allow you to sell something you have a surplus of now and buy something else later which you dont need yet.
That is true, however, I would still question the value such an currency would have. CIC is powerful, as it is the only way to ever build anything. You don't really get enough of it. If you have plenty resources traded away, you use that CIC to build Mil IC and gradually you export less as you gain more equipment.
Trading-only money is useful as an balanced medium of exchange if you sell 40 oil and buy 40 rubber. It's not that useful if there are large imbalances. This may not be intuitive so lets make an example:
- You have plenty resources, and since the only thing you can do with excess resources is to try to trade them, you try to do it, earn money. With this money, you try to buy equipment. (if we have equipment sales added to the game)
- For the equipment-producing country, if they too have plenty resources - the money is not useful - result is that they won't sell, no trade is being done.
- If they lack resources - they want money to purchase it. However - what do they want the resources for? Producing equipment. So they are kinda indifferent between purchasing resources to make more equipment and then trade away part of that equipment and just not trading since they end up with an similar number of equipment for themselves. This can partly be remedied by having very severe penalties for resource lacks. So that the optimal strategy in cases like that is to trade away enough equipment so that they can afford resources.
- Additional case where trading isn't that useful; country has poor tech and shortage of resources. Few countries would wanna buy their equipment, hence they don't get money. THus they can't really buy resources and will have a chronic shortage unless they conquer it.
The result no matter how you look at it is less overall trade. And under no circumstances is the money as useful as getting CIC even if you can stockpile it.
If you use either the more advanced money I proposed, or keep the CIC as the currency, and have an abstracted debt/reserves (I made that for our mod) you can do everything you wanted without the drawbacks I outlined above.
