Is that the one that gives you envoys if you convert them?
Yeah, I think that helps.
It is
Religious Unity that grants 1 Envoy when converted.
With Rise & Fall,
Papal Primacy changed and is now granting 200 religious Pressure per Envoy to City-States.
Aside: the proposed change always felt odd to me. It is the only Founder belief that doesn't reward you from converting cities. It feels more like a Enhancer belief, which is supposed to help to spread or defend your religion. I guess it is on purpose: you sacrifice the "profit" belief for another "spread" belief. Kind of the same with Crusade, which is a Enhancer belief, but feels more like a Founder belief: you are rewarded with better military capabilities when the foreign city is converted, but does not help to convert cities.
But in Vanilla, Papal Primacy bonus is:
Type bonuses from City-States following your Religion are 50% more powerful.
For example, Kumasi gives +1, +2 and +3 Culture to Amphitheater, Museum and Broadcast center. If Kumasi is converted and you picked Papal Primacy, therefore you will enjoy +1.5, +3 and +4.5 Culture instead. To every buildings in your empire. Even if the city itself don't follow your Faith. This is completely insane.
Even if you only had 6 Acropolis with a Amphitheater and Museum, it will give 6 × (0.5 + 1) = 9 additional Culture when converting a single Cultural City-State. In order for vanilla World Church to give as much (+1 Culture for every 5 foreign followers), you will need 45 foreign followers: basically converting a whole Civilization.
But those are the numbers with the Ethiopia Pack. Here are the differences between Vanilla and Ethiopia Pack.
Cultural | Vanilla | Ethiopia Pack |
1 Envoy | +2 Culture in the Capital | +1 Culture in the Capital and to Amphitheaters |
3 Envoys | +2 Culture to Theater Squares | +2 Culture to the Consulate and Museums |
6 Envoys | +2 Culture to Theater Squares | +3 Culture to the Chancery and Broadcast Centers |
Trade | Vanilla | Ethiopia Pack |
1 Envoy | +4 Gold in the Capital | +2 Gold in the Capital, to Markets and Lighthouses |
3 Envoys | +4 Gold to Commercial Hubs* | +4 Gold to the Consulate, Banks and Shipyards |
6 Envoys | +4 Gold to Commercial Hubs* | +6 Gold to the Chancery, Stock Exchanges and Seaports |
* : Only Commercial Hubs. The Harbors do not enjoy from it in Vanilla.
Even if the Ethiopia Pack can reach higher yield, the Vanilla way make enjoy from them earlier. You chopped the Acropolis in a foreign continent? No need for buildings, you can already enjoy the Culture from City-States. You picked Papal Primacy and converted 4 Cultural City-States? Well, enjoys your free +24 Culture!
As the late-game building's cost is higher in vanilla, while most tile improvements were made better starting Gathering Storm (including Industrial Zone), getting most buildings in cities is way harder or costlier. It is far more easier to just chop a Commercial Hub (which gives the Trade Route directly in Vanilla, without the Market) and forget about their buildings as it is not worth it.
You just have to be careful about Spies, but since they target the city with the higher GPT, you can figure out which one will attract all the Spies, therefore put one to defend.
But definitely Reliquaries is the way to go.
What you choose for your second tenet is up to you.
Every time I picked
Reliquaries, I couldn't make it work. Only Arabia is going to have a Religion and Saladin seems to completely ignore Apostle. Sure, I could go after some Missionnaries he tends to summon in the first 75 turns, but once my Apostles were parked in his empire waiting to die, he just stopped to buy Missionaries. He stockpiled the Faith (1000+) and did nothing with it.
I was unable to get a single of my Apostle killed with Mont-Saint-Michel for an extra Relic. You basically depends on how much Relics were generated from Tribal Village. It is very situational. Yet... all other Follower Beliefs are not great either.
From all the Follower Beliefs, I don't think there is one that would help a lot. I think Jesuit Education is probably the next best, as it allows to buy a few Amphitheater and Archaeological Museum, as you might want to save the Gold to buy the Archaeologist, or save to try to get Mary Leaky (+200% Tourism from Artifacts). Zen Meditation could help with Amenity as our starting continent does not have much Luxury Resources and the AI are selling them at an exorbitant price, but low Amenity maluses are not as detrimental in Vanilla.
Choral Music and Divine Inspiration don't feel right, as Culture isn't the bottleneck and the few Wonders we could build may give us more Faith, but that Faith isn't as useful (National Parks are pricey as Naturalists are 2.5 more expensive).
There is still Work Ethic, that could help to build Wonders in main cities or go for more projects.
I had a second go with this choice and shaved about 50 turns off my game largely b'cos I was able to DoW Holy War with Arabia twice. No capturing of any cities. Just pillage and plunder.
But I know this largely depends on the RNG goddess (and where you forward settle Arabia).
I went very peaceful every time with all Alliances with everyone. I should try a war approach, as Kongo is consistently Cultural, and Egypt sometimes outperforms in the late game (but not always?). It would fuel my economy better, so let's see it compensate the lack of modifiers (no trade-route, no open borders), and the inability to buy Great Works from them.
From all the Leaders they picked, they only picked Vanilla. And from all Vanilla, they picked the one with Culture: Brazil (Theater Square/Rainforest, Great People), Egypt (Wonder, Sphinx), France (Wonder, Château), Kongo (Slots, Great People, Artifacts), Rome (free Monument, but we all start with free Monument...), and Russia (Great People, Trade).
The only odd one is Arabia. Probably to force to have two religions in the game.
Oddly, they didn't pick China (no ancient/classical Wonders, but there is still the Great Wall), America (Film Studio, but really gimmicky) and... England as vanilla England have "British Museum" as an ability instead of "Workshop of the World".
