There have been arguments recently over the idea of a "diplomatic currency" being implemented in the game as a resource. The way it works now (beta 3C) it is simply used as a way of getting something for nothing from the AI players – so much so that it is "consumed" when traded to an AI player, so they don't gain their own capital out of the deal.
A lot of the arguments seem to be based around the debate of whether Elemental should be balanced more towards multiplayer or single-player play, but I think that's beside the point. If diplomatic capital could be "spent" for some gain by a player, then it would be useful both in single player AND multiplayer. Even if it is used (as it is supposed to be) mainly in exchanges between players, its value as an item of exchange would derive from the fact that it has value on its own.
Once players have something to gain from trading other things for DC, there is no need to "enforce" its value on either human or AI players. For AIs, this means that there it will not disappear when traded to them – an AI player that trades something in exchange for DC will gain DC that it can then hoard, trade to other human/AIs, or spend for its own benefit. It will work by the same rules as other resources like gold or metal.
For humans, this means that there is no need for the ability to "force" human players into accepting deals/treaties with DC, as too many people have proposed. I am strongly against this idea as it is very unfun for players who are forced into doing something they don't want. On the principle of reward > punishment, if players are rewarded for gaining diplomatic capital, then they will give trade items and treaties for it willingly, but they will have a choice in doing so – and meaningful decisions to make are the source of depth for strategy games.

Those of you who have been following the Civilization V previews know that CIV actually had a very similar issue with the value of its gold resource. Since gold didn't have many "lump sum" uses it could be spent for, there was little reason for players to save up or trade the resource rather than channeling it all into science. So the Civ devs solved this by allowing gold to "buy" land tiles for cities' areas of influence. Now there's a reason to hoard gold, and a reason to trade other things for it, which is equally relevant to humans and AIs. I think this demonstrates exactly the point I'm making for diplomatic currency in Elemental.

Even if the game is 1v1 and there is no question of players exchanging DC between them, then a player would still have something to gain from producing and using the resource. So, what kind of utility can diplomatic capital have that doesn't depend on another player?
- I like the idea that's already proposed, that DC can be used to recruit NPCs in place of gold. This is very fitting for a "diplomatic resource", but it isn't enough on its own as the map eventually runs out of champions.
- Diplomatic capital might be used to boost cities' population growth, as a kind of temporary prestige. This would be an equivalent to Civ-V using gold to buy land, but it would work with Elemental's premise that city influence is based on population, and would be limited by the maximum influence you could get from population, so one city couldn't control half the map by using DC.

Once you have more uses for diplomatic capital, it would also be worthwhile to have more ways to earn the resource.
- One idea I very much like is to give it as a quest reward, representing friendships gained, favors owed etc.
- Another way is to have a champion ability that "produces" DC. Currently we already have merchant champions that produce gold, inventors that produce research etc, so why not diplomat champions that produce diplomatic capital? This could also be a selectable ability for sovereigns.
- I don't know if it is still planned that the Empires factions will be able to produce their research and arcane research resources by training special "tutors" and "lore masters" units rather than by making buildings, as was mentioned in a dev journal. If this is the case it would be perfect for them to also train "envoys" that produce diplomatic capital in the same way.

Sorry for the wordy post. I want to encourage people to put forward suggestions for ways to earn diplomatic capital and ways to use it. With enough interest maybe the devs will be convinced to expand on the diplomatic currency idea, which is one of Elemental's more unique and intriguing concepts.
