我都不求不降种族关系，只要改成不是永久降关系就好了。星陨这个版本这个设定太扯了，我夷平一个居民点，这个种族记我一辈子。

还真有，就是不知道好不好用。
mod名称：tall empire (singular city support)
作用（介绍）：
I have seen a few mods that try to discourage Colonizer spam. But each one merely shifts the problem, either by making the colonizers cost more, or reduce the places where they can colonize (like Return to Dust).
So, I set out to find a way to reward staying on a single city, opposed to expand as fast as possible.
Soon, though, I realized why there was no mod in that direction. Because it is damn hard to pull off. I had to repurpose the race relation system for it, actively gouging it into non-functionality.
So, this mod abolishes (due to necessity) the race relations, replacing it with a 'bonus' system when only having a single city.
- negative race relations have no consequences, but disable the colony bonus (friendly and adored still give unit morale, but everything else was removed).
- Accepted doubles your colony income, Friendly is 4x and adored is 6x.
- you start with 0 relation to your own race, and for each doctrine slot unlocked, you get a 100 reputation bonus, up to 600 (adored).
- each colony you possess reduce race relation to said race by 600
- conquering a colony gives a 3-turn lasting 600 relation bonus, long enough for the average race to raze the city.
- razing a city adds 200 to that race relation for 15 turns, elevating your relation to the next level.
- other actions do no longer change the race relation (includes migrating, declaring war/alliance/...).
- this includes the landmark doctrine, the Charismatic Trait and Disinformation Campaign.
These have their effects replaced:
-- Landmark Doctrine gives relation modifier for AI, morale bonus for troops and happines for cities.
-- Charismatic know the start positions of players and have a 200 relation modifier when interacting with AI
-- Disinformation Campaign reduces the relation with AIs by 300/100, as well as giving units -200 morale when being successful.
Sidenote: Happiness events were changed, first stage is always food, second stage always food or production, third stage is always knowledge, but also provides a passive boost to the other recources.
TL;DR: Race relation has no longer an effect, except boosting your colony productivity when having exactly one city.

KNOWN ISSUES:

- descriptions are misleading. At some point I will reform them. Maybe.
