SV T209
Map
Weird layout where Shipbuilding was required to meet the 3rd AI on the landmass.
Lots of spots for 4-adj campi
Poland
This civ doesn't really have any abilities that help it pursue a SV which fits the meme "Poland cannot into space".
Standard adjacency for Holy Sites and buffed trade routes from Sukiennices are minorly useful, but require building both types of infrastructure (and running both policy cards) to really benefit from them which make it impractical.
No AI had founded a religion on the continent, so I couldn't benefit from any buffed relics.
Also sadly, encampments and forts do not culture bomb beyond the 3rd ring. This is the only ability I could have seen as especially useful.
The conversion of a military slot to wild card makes the government types with lots of military slots more flexible (Autocracy, Monarchy, Communism, etc.)
Run
Missed the Earth Goddess pantheon.
I made a joint war with Gilgamesh against Shaka so they would beat each other up before going to war against them.
Conquered the whole continent with 4 Horsemen and 2 Swordsmen. 3 Knights helped later with Gandhi. No AI had walls.
I delayed exploring the other continent, because I wanted to wipe mine before meeting the other AIs (and not get negative modifiers).
However by doing so, I found out too late that there was no cultural city-state on the map. Culture was thus the biggest bottleneck in this game.
Yet, since there was 4 scientific city-states on the map, the base science per turn was higher and thus the moon landing more powerful. I was thus able to reach Optimization Imperative in time.
I only did some pillage wars on the other continent.
2 spaceports were bought with faith.
Since this is a lower difficulty game, I was running short of gold a bit at some points during the game.
Recent patch changes
I tried to experiment with taller cities in this game (without great success). Getting 1 city at 15 pop in time for Urbanization is usually no problem, but getting multiple ones at 15 pop early enough to matter is a different story. Without Magnus food chops and/or internal trade routes, they come too late to matter. Increasing housing also necessitates of lot of resources. Only 3 of my cities reached pop 15. A 4th could also have possibly reached that threshold. In the future I don't think I will aim for more than 3 pop 15 cities if I find some spots with food resources to harvest.
The changes to happiness made me run the Liberalism card most of the game after unlocking it. Colosseum becomes a must. I should also have built the Forbidden Palace/Big Ben for the extra policy slots. I also refrained from conquering the other continent because maintaining 20 tall cities content was already a challenge.
Rationalism now provides very little additional science (+10 to +20 bpt at most) when first unlocked (which is pitiful compared to what you can get from Natural Philosophy at that point in time). Unless you have extra policy slots, it's not worth running early on.
The change to the Public Transport policy card makes it harder to buy an additional spaceport with gold.
The slower pace of the game due to overall lower science output and the recent changes to eureka make it easier to get all eurekas in time. I think I only missed 2 this game (Build 2 Biplanes and Build 2 Drones).
AI
Maybe it's only anecdotal, but the AIs now seem to build more units when they are at war / under attack.
Shaka razed Jerusalem early on. An annoying behavior introduced in the recent patches (maybe linked to the amenity changes?). I personally have no problem with AIs conquering city states, but if they systematically raze them, it's another story. Especially, since cities are instantly razed in this game.
When the first World Congress triggered, I had not met any AI on the other landmass yet. The luxury proposal came up. All AIs voted for banning Cotton despite the fact there was no Cotton on their landmass. They shouldn't even know what Cotton is at that point.
