Since we reached T135 here is how I did with a straight 7 city NC on turn 137 for reference:
Good job with those ninjas captures ! Very clever, very efficient. I was a bit disappointed of our state at T90 but we're back in the game. This happiness and gold will allow us to catch up in infrastructure and population.
Alright moving on to my play:
T135:
Capital should have made writer's guild ! Switching to that now.
Douglas and Nantes are really lagging, the basic infrastructure isn't there (aqueducts) while it has things like universities. I use 800gold to rush two aqueducts.
This is where I really dislike the patronage choice. We have not started to even make amphitheaters and on top of going for a CV we need our UB for happiness. But we don't get the cultural centers bonus. Sadly with our low culture we cannot wait for the policy. Switch Nantes and Dublin to Amphitheaters. Truro and Cardiff are making good gold so I let them on markets.
To help with low culture we have brussels that can be allied for 500G. It would also give us access to gems and complete one wltkd. Sounds like a great deal for next turn.
I don't understand why we're not working (again) Sinai. We don't even have enhanced yet ! Fixing that and requesting a Prophet out of faith.
There is a 6 iron tile near nantes that we should have gotten earlier.
T136: I go ahead and ally Brussels with also gifting an archer for 10extra influence which was behind and just barb spotting.
If we want want to attempt to Ninja Seoul we need a Knight I think. Shaka is willing to attack Sejong.
T137-138
We get Banking. Since we have workshops everywhere it's a good idea to unlock the Ironworks.
Dublin switches to Caravan.
Gustavus makes the Globe Theater.
T139
Open Rationalism.
I notice Sidon is on stop unit spawning ? Why ? If the units arent interesting just remove them and get back some gold or gift them to CS.
Cardiff makes an Amphitheater after the market.
The writer guild is finished and staffed, I make a garden in the capital considering the concentration.
Thankfully Sofia gift us a Mandekalu cavalry so a knight isn't necessary. I bribe Shaka to attack Sejong for Salt + 4gpt, let's hope it creates opportunity, Shaka is the only guy really likely to create this anyway. This unlocks pearls from Sejong which we exchange for a wltkd.
T140-141
We get our first great artist which we make a great work with. We're likely to mostly fill the hermitage.
We finish Machinery. I think the best option is to put Ironworks in Dublin since its the city with the less stuff to build right now.
Leaning Tower is very unlikely so I go Architecture for a shot at Uffizi.
Nantes works on a Ceilidh Hall.
T142 We get a Prophet
Sadly Shaka decides to also declare war on Genghis... so it's likely he won't touch Sejong at that point.
We finish a caravan in Dublin and I send it to Nantes as it is lacking in food.
So I enhance and here is my thought process for 2 unconventional choices. There are only 3 good follower choices. Guruship, Feed the World, Swords into Plowshare. Guruship is a guaranteed 2.2 to 2.3 production in every cities (with modifiers). After calculation swords is between 1.2 (Cardiff) and 2.8 food (Capital) and doesn't work if we ever go to war. Feed the world is between 0 and 2 food until we can get shrine and temples absolutely everywhere. Considering we are also late in buildings I picked us Guruship.
We also good have considered the hermitage stuff for 20ish late game tourism but we're like 25turns away from hermitage anway...
For the enhancer we basically have better spreading ones or reliquary. I think we're screwed at that point for better spreading and we will start hoarding faith in not too long so let's give Reliquary a shot.
T143
Bismark makes the leaning tower
Sejong is plotting against us
Ramkhaeng declares war on Genghis too
Douglas finishes University and makes an amphitheater
Capital finishes Garden. With 4 turns before Uffizi I make a forge: 2 Irons and the bonus applies to archaelogists.
T144
Shaka is definetly busy with genghis and seems to focus on him rather than Sejong. Oh well.
World fair in 9 turns, as a result I focus Dublin in production so that it can finish the Ironworks.
T145
One of our capital food TR expired, I use it for Dublin, the capital is still at a good food per turn (+20) for a liberty/wide game, I suggest using the gold TR in 14 turns to feed the capital.
Cardiff builds StoneWorks, it's cheap and efficient.
T146
Seijong makes Taj Mahal.
Bismark asks us to help against Shaka I refuse
T147
We get Architecture but I've been a bit too optimistic I think. 18 turns is really long so change of plan.
Now I look at the incoming world fair in 6 turns with the 2 RAs incoming in 2-3 turns. I think getting Scientific at that point would not be that useful considering we'll be in a production lock for some turns since I think we should pull all our effort into the world fair. These 2 RA should be way better suited toward chemistry which will help us overall more than a too early scientific theory.
For the same reasons Douglas starts on stable.
T148
Germany is angry for us being friend with Shaka
Truro makes a Circus
Cardiff makes a Colosseum
T149
I accept a RA with England. We have not paid enough attention to potential RA apparently as I remember to do so and sign a RA with Sweden.
We get our first great writer to get a great work.
Our first RA finishes with Siam which I renew. The RA gives us 2 techs toward chemistry.
T150
Second RA finishes and gets us 2 turns away from chemistry. This will allow us to get it exactly when the world fair comes.
World fair soon so I start quick buildings:
Circus in Nantes and Colloseum in Capital
Shaka is likely to finish Genghis Khan.
Pointers:
We are currently at -1 happiness. We have deals coming to terms, just don't renew the Sugar deal with Sweden and renew the Silver deal with Germany, then the happy buildings should be there next turn.
Be ready for a full focus on World Fair (all cities at the first turn on it + working all mines).
Allying Kabul could be a good idea since it has bonus for gifts.
I would otherwise start to hoard gold for possible rushs.
Regarding the next phase after world fair there are multiple ways to deal with it. My approach would be to select 3 cities that have a good production and can make a forge (and which aren't the capital):
Dublin, Nantes, Cardiff
Make that forge just after the world fair (you will be able to prebuild it for a turn or two it seems). Meanwhile get Economics and bulb Industrialisation with the incoming scientist. Since we play NQ map on default we're guaranteed Coal in the capital (and anyway with 6 cities it's likely to get some). Improve that asap and go for schools. The 3 cities make 3 factories so that we get both the ideology and archaelogists factories. Put schools somewhere in there as well as amphitheater/ceilidh hall (other cities make school before factories).
Go archaeology after schools then switch to Radio for the wonders and keep Oxford for a late game tech.
We also have to put down Observatories at some point... but it will probably be after schools.
