Could we see the pluses and minuses of diplomacy, just like in Civ 4?

I think it would be really cool if civilizations that share the same religion would be more likely to join each other in wars, expecially if the religious host civ declares war.

In the main comment thread "Umbrae" made an excellent suggestion about giving players (and perhaps AIs) a "praise" button in the "discuss" option. It would function exactly opposite of "denounce" giving you cred with the civ you're praising.

My added suggestions would be:
1) "cred" you get for "praising" another civ is multiplied upwards (e.g. x 1.2) if you are doing things the target civ appreciates (freeing captives that belong to them, giving them money or trade items when they beg... er, I mean ask, choosing the polite dialogue options when talking to them, etc.) The multipliers shouldn't be much since they could stack on quite a bit.

2) "cred" is multiplied downwards (e.g. x .8) if you've recently done things the target civ doesn't appreciate (keeping one of their captives as a worker, refusing to help when they ask for money or items, being rude in dialogue choices, etc.) These multipliers should also stack for each instance within, say, a 10-turn period in a normal length game. Also, a civ in "guarded" status vs. you will multiply the cred downwards steeply (e.g. x .25) so that a player cannot simply "praise" its way quickly out of guarded status with other civs. (You could do it, eventually. But it will take so long that chances are something else you do will affect the other civ's opionion of you far more profoundly.)

3) Praise option should not be available to you when the target civ drops into "hostile" status with you. Edit: and, of course, obviously not available when you are at war with the civ. Now that I think about it, it shouldn't be available during the enforced 10-turn peace treaty as the target civ is likely to be in a bad mood at the time and not receptive to any flattery.

Helping protecting a Civilzation from attack (E.X. Barbarians or other Civ's attacking) will increase your friendship with that Civ, or maybe giving you money for thanks.

On a lucky chance, helping protect a City State from attack will impress the other civ.

(Maybe getting rid of the ability to put boats inside your city.)

Merging, if a City State loves you ALOT they will merge their city with you. Upside: Happyness. Downside: Very expensive.

Being able to trade with city states.

Being able to buy land from other civs and city states.

Protecting a City State from attack will impress other Civs and City states and give them the appeal that your trust worthy.

As well as the existing map trading option, I think it would be good to have something akin to the research agreement, in the form of an 'Exploration agreement". Basically, each side contributes gold, and then for the duration of the agreement random tiles that only one member has revealed become viewable to the other. The tiles that are revealed are random, but must be adjacent to a tile that's already revealed (So no tiles in the middle of nowhere). If I need to explain more just let me know

I would love an option to simply turn off research agreements, without having the trade option..

I only wonder if it would be possible to implement other language versions as well, because it really looks bad when you've got all the game in one language and this little piece of UI in English. If so, I would gladly help with translating texts to Polish, though I cannot guarantee I would do it instantly. ;)

My suggestion would be to make a vannila version of this mod.

maybe you could add some type of "appease barbarian option" or "what units would you like to trade"

I would love to see a vassalage/serve option, nothing like making another civilization work for your empire, even if they are willing or not haha.

Just popping in to say your suggestions have been read. Keep them coming!

No more warmongering, either in this mod or as a seperate one. Settling a city near another civilization may make them invade any only capture that city. If barbarians capture a city (also make them stronger) they will become a random unused civilization.

There's one feature I miss from Civ III (don't remember if it was in Civ IV) where if one of your cities bordered an AI city, and your culture rating was much higher than the AI's, there was a chance that the AI city would defect to your side.

would it be possible to be able to pay civs and have them like you more like with city states but can only do it if allys and the ai can do the same for the us give us money and we have options like thanks want to DoF,no thanks but thanks for the offer, or no i dont want your money and is there away to add more good things with the ai i can never get anothuth so they dont attack me later in the game even if we have been allys from the start

ideas for +'s to relationship:
1. Seperate +'s each time you give an ally aid
2. Purchase +'s to relations with gifts of cash or luxuries (the + depending on the amount much like city states) (on a side note it would be great if the game would slightly lessen the amount of gold needed to win over city states)
3. Include an option for foriegn embassies. After you make a DoF, make it an option to create mutual foriegn embassies. This would be a + to relationship and you could even include random events based on embassies. Embassies would give you sight of their capital and what their producing in it. Embassies might also offer a bonus to the percentage of gold from open borders and DoFs.
4. Like city states, a nation could give +'s to relationship based on the amount of aid in a battle. You killed 1 unit in the ancient age you get a +; you killed 3 units in the classical age you get a +; so on and so forth. (Those numbers are just an example.)
5. Give a + for gifting units. (This + might also depend on the age and amount of units)
6. Give a + for the renewals of alliance or DoFs. In other words, the longer you've been friends, the greater friends you'll become.

Ps: this all looks like great work so far. I can't wait for all this to take effect. Its always been frustrating for me as a player when I build up a rich empire based on trade and canny alliances just to have it all blow up in my face in later ages because the diplomacy AI is icompotent. I could be trading three major resources with a neighbor and ally, selling them strategic resources with a research agreement to boot, and they'll suddenly inexplicably denounce me and refuse to renew an alliance because one of our former mutual alliances denounced them, so now I'm friends with the enemy or some nonsense. Anyway goodluck!
