Community Ideas: VP Leader-Specific Diplomacy

Hello all,

For this beta version I added some diplomatic approach weight to three leaders: Montezuma, Gandhi and Ashurbanipal.

As of yet, there doesn't seem to be any complaints about this, and it seems to be performing well, so I'd like to expand this and give each leader their own unique approach bias, and I'm requesting ideas from the community in order to do so.

The concept is to have every civilization leader approach other civilizations in a way that factors in their civ's unique traits (to a degree).

This is similar to the Civ 6 agendas system except less er, dumb. The approach tendencies' objective is to allow the AI leaders to behave more intelligently by exploiting their unique strengths; the Civ 6 agenda system (especially when it comes to random agendas) is an oversensitive flavor mechanic that results in erratic, self-destructive and hypocritical behavior.

I have completed the approach biases for three leaders (the info listed here is as of the next version, not the current version) which can be used as examples:

Assyria (Ashurbanipal)
Treasures of Nineveh: Gain a technology or obtain a large Science boost upon conquering a city, +3 Science from Great Works

Uniques: Royal Library (School of Philosophy granting a major Science boost, and Great Works of Writing give XP to newly constructed units), Siege Tower (unique type of unit available at Military Theory, gives a major boost to units sieging an enemy city; only 2 may be active)

Approach Change:
does not apply if all techs already researched
Towards civs with more techs, +1x WAR bias + the tech count difference
Towards civs with less techs, +1x FRIENDLY bias + the tech count difference
Towards civs with equal techs, +1x NEUTRAL bias

Rationale: Ashurbanipal's ability to steal technology and Science should increase his desire to go to war against those with technological secrets to steal (especially when you consider his UA and UB). This approach change incentivizes him to go to war against civs he has the most to gain from by DoW'ing, with the backing of civs he has the least to gain from by DoW'ing.

Aztecs (Montezuma)
Sacrificial Captives: Gain Gold and Faith for each eneny unit killed, Golden Age starts on favorable Peace Treaty

Uniques: Floating Gardens (better Water Mill with large Growth bonuses), Jaguar (better Warrior, heals on kill, bonus in forest and jungle, promotions stay on upgrade)

Approach Change: + 1x WAR/HOSTILE bias pre-Renaissance Era (this is impactful as he has a high WAR/HOSTILE bias compared to his other biases)

Rationale: Montezuma benefits a lot from war, particularly in the early game, and should be going to war very often during this time.

Special Trait (Ximicacan): As the most aggressive leader in the game, Montezuma gains an additional +1x WAR/HOSTILE bias unconditionally, but also ignores most warmongering by other civs (diplomatically, that is; he still gets anti-warmonger fervor). Being the most notorious warmonger in the game himself, he doesn't mind it (otherwise he'd have few potential friends).

India (Gandhi)
Font of Dharma: Cannot build Missionaries, Prophets cost less faith, start with a Pantheon, each majority religion follower boosts Growth and Religious Pressure

Uniques: Harappan Reservoir (Aqueduct which boosts Food-heavy tiles and Farms with Production bonuses), Naga-Malla (Cuirassier but available earlier, stronger, and needs no resources)

Approach Change: +1x FRIENDLY bias to players with no warmongering penalty (as far as he's concerned, anyway)

Rationale: Not only does this fit Gandhi's personality, it benefits him strategically. India's strengths lie mostly in building huge cities with strong infrastructure, and the religion game. Warmongers are a threat to both of these pursuits.

Special Trait (Nuke Happy): As the friendliest leader in the game, Gandhi gains an additional +1x FRIENDLY bias unconditionally. However, he becomes insanely aggressive upon constructing nuclear weapons (can be disabled), and has no hesitation to use them (applies even if disabled).

Note: I'm not planning to add special traits for all leaders; I only added these two, mostly for fun. Am open to suggestions about them, however.

Where the community comes in!
I need some help coming up with appropriate and cool ideas for all the other civilizations in the game!

If you have any idea for a mechanic that would fit a civilization well, please post below! Include the leader name, approach change and reasoning.

Posting guidelines:
1) Serious suggestions only, please.

2) The approach bias should serve the civilization strategically in some way and therefore make the AI smarter. If it also ties in to the leader's historical personality, that's great, but that's a second priority.

3) The approach change can have conditions attached to it (for instance, "+1x FRIENDLY bias if in the same era").

4) There are seven approaches: WAR, HOSTILE, DECEPTIVE, GUARDED, AFRAID, FRIENDLY and NEUTRAL. Each leader has a bias (in short, an amount of weight added or removed when various conditions make a certain approach favorable or unfavorable) for each of the approaches, which is randomized a bit from game to game. You can find out more about the approaches and what they do on this page: https://civ-5-cbp.fandom.com/wiki/Detailed_Guide_to_Diplomacy

5) You are welcome to contribute your thoughts on others' suggestions.

Let me know of anything interesting you can come up with, and thank you to everyone who helps!

Don't worry, this will take a long time to decide upon and then to code. It won't be in the next version, and there will be time to settle and fix issues before then.

I'm starting to solicit ideas now precisely because it will take a long time, in fact.

Additionally, this will only be one factor in a large calculation of many other factors, so the change would not be overwhelming.

Thank you to everyone who has suggested ideas!

 

Approach does impact trade deals, but I think the current deal AI checks largely do not factor in the AI's false approach (in this case, FRIENDLY) for item valuation.

Understanding the deal AI is something I'm working on at the moment; your suggestion would be possible, though.

 

He doesn't; approach changes gradually on a curve. And remember, this is only one factor of many factors, so it will not by itself be decisive in what approach the AI takes.

My thought process was that players benefit from having friends, and that being a bit more friendly towards lower tech civs would incentivize him to pursue attacking the players he can gain the most from DoW'ing, with the support of civs he can gain the least from by DoW'ing. AIs already are more likely to attack players who have a weaker military.

 

https://civ-5-cbp.fandom.com/wiki/Detailed_Guide_to_Diplomacy#Approach_Biases

The values are listed in this section, and are randomized by +/- 2 every game. You can see the approach calculation for the full details, but tl;dr - adding a bias once means adding a number between 1 and 12 (although for most civs it's between 1 and 10).

 

I believe Random Personalities swaps in the diplo biases of a random other civilization in the game.

If you mean these specific leader weights I'm planning on adding, then currently no - because the code checks if the leader has the specific trait; e.g. rather than checking for "LEADER_MONTEZUMA", it checks for "Player Traits: Golden Age on Victory", and adds strategic weight accordingly.

If it was swapped randomly it would result in somewhat erratic behavior; although, I suppose that's the point.

 

Those wouldn't meet the "strategically intelligent" criteria, especially the first one.

It's not quite an "agenda" per se, more of a behavioral tendency intended to help the AI maximize use of their UA. The approach mechanics are not really shown to the player other than through Opinion modifiers, and I'm not sure how to go about doing so; however, it'll certainly be documented somewhere.

I've thought of trying to make an actual agenda system based on the Civ 6 one as a modmod, though.

Thank you for your ideas!

 

Wow, that's a lot of ideas. Kudos!

If I ever do make an agendas modmod, I'll come to you for help, haha.
