[LOT] Legitimacy Over Time

This is a mod designed to enhance the gaming experience without becoming completely unbalanced. If you’re not satisfied with how Paradox implemented the legitimacy system, this mod might be for you.

---

Isn’t it fitting for a ruler to gain legitimacy over time? If a ruler is competent enough to stay in power for years and years, doesn’t that in itself prove their right to rule to some extent?
This mod represents the idea that the longer a ruler remains in power, the more their right to rule and thus their legitimacy increases every year.

It allows all rulers above age 16 to gain legitimacy over time. The calculation is quite simple all rulers receive legitimacy yearly and depending on the Culture Era, and here’s how it works:

Tribal Era:

• Count: Years as Count * 0.5
• Duke: Years as Duke * 1
• King: Years as King * 2
• Emperor: Years as Emperor * 4

Early Medieval or later:

• Count: Years as Count * 1
• Duke: Years as Duke * 2
• King: Years as King * 4
• Emperor: Years as Emperor * 6

As a ruler, it is important to maintain good relations with your strongest vassals because they are pillars of the realm and help fortify your legitimacy over the throne. Having good or bad relations with your powerful vassals can impact your yearly legitimacy gain.

Here is a breakdown of this new system:
You need to have at least 60% of powerful vassals with a positive opinion to receive a flat 10% gain on your yearly legitimacy. If you have less than 60%, you will receive a % deduction per negative relation (5% in Tribal Era and 10% in Early Medieval Era or later) with a powerful vassal, which will be subtracted from your yearly gain.
If you have 0% of powerful vassals with a positive opinion, you will start to lose legitimacy yearly, equal to the number of powerful vassals with a negative opinion multiplied by 3 in Tribal Era or 10 in Early Medieval Era or later.

Here is a list of the required number of positive relations (equal to 60%) to gain the 10% increase:

• Count: 2 out of 3 powerful vassals
• Duke: 3 out of 4 powerful vassals
• King: 3 out of 5 powerful vassals
• Emperor: 3 out of 5 powerful vassals

NOTE: The percentages does not affect legitmacy gain from outside sources, only affects this mod.

You now have game rules that you can modify to suit your preferences:

• Reduce legitimacy gain by 25%, 50%, or 75%.
• Enable or disable the Powerful Vassals Opinion Matter system. Note: By disabling this feature, all Rulers cannot lose legitimacy in the current version, the Ruler can only gain it.
• Grace Period for all rulers to start being affected by the Powerful Vassals Opinion Matter system can be set to 1, 2, 3, 4, or 5 years. The default is disabled. Note: Disabling the Powerful Vassals Opinion Matter system will also disable the grace period.

Based on my tests, it appears to be compatible with all mods, but I’m not entirely sure. If you encounter any issues, please report on the Bug Report thread.

1. Is this mod completed ?
   Not yet, still need more work to do. Check the "To-Do/Ideas" to know more.
2. Can this be used in multiplayer?
   Yes.
3. Is this save game compatible ?
   It should be. However, in your existing save game, if you have been a ruler for 1 or more years, the new version (v20240813 or above) will reset those years to implement the new system. But when you start playing with your heir, everything will go back to normal.
4. Does this mod affect the AI ?
   Yes.
   Starting from version v20240830, there’s a system where the AI starts improving the opinion of powerful vassals if it has been losing legitimacy for several years. This makes the AI ‘aware’ that it can’t afford to keep losing legitimacy for too long. If the AI isn’t losing much legitimacy, it will only consider improving relations if it doesn’t already have another agenda. Otherwise, it’ll keep doing its usual stuff.

This is a list of many things that I’m currently implementing or might implement; not all might be implemented, some might be scrapped. Want to make a suggestion or share an idea? Just Click Here.

1. Adjust the gain multipliers for all title tiers. Might be decreased or increased. (Number values are still under consideration.)
2. High Dread can cause penalties to the yearly legitimacy gain and might even make you ineligible to gain yearly legitimacy. (This feedback came from the community. If anyone thinks it should work differently, please post it in the Feedback thread.)
3. Some actions, such as kidnapping a vassal or having bad secrets discovered (such as murdering a vassal), can result in penalties to the legitimacy gain. (Idea came from the community | This one is proving to be very hard to implement, so there is a chance it will be scrapped. Sorry!)
4. Legitimacy penalties if the ruler loses land, or possibly land within the primary title (still need to think more about it).
5. Legitimacy gain value is reduced according to the ruler’s legitimacy level. For example, if a ruler is at Legitimacy Level 3, they receive 4 * Years as Ruler. When they reach Legitimacy Level 4, the legitimacy gain value changes to 2 * Years as Ruler. This is only an example, and all values are under consideration. (Idea came from the community.)
