OK it is time to make a decision about wonders, so lets see what's going on in our cities.
We have 6 workers now. It is not bad because we are industrious, but with only 5 cities we want to grow even faster then usual. We also have more roads to build due to loose spacing and we'll have to build a few colonies to hook up luxuries and maybe horses. We also have some nasty jungel and march tiles in our borders. So i think we need quite a few more workers.
Istanbul is now making 10spt and 5fpt at size=8. We can build a sword and a worker very 4 turns there. We can also build a wonder there, if we improve hills we can get it to 15-20spt. A library there will also be nice even though it doesn't need to expand borders - it'll help a lot with research cause Istanbul produces almost 50% of our beakers.
Edrine is building the Pyramids now and has accumulated 151 shield. It can buil TGL in 28 turns or SoZ in 6 turns. We are running 40% lux now because of that city. If we lower it to 30% and hire a scientist in Edrine instead of working the forest tile we gain 3 beakers per turn and 2 coins per turn (Writing 1 turn faster). The wonder build in Edrine will only be slowed a little bit, because one of the shields was lost due to corruption and food doesn't matter cause it is at size=6 and needs an aqueduct. Basicly trading 1 shield for 5 gold - well worth it imho.
Bursa is building barracks now, but it is not very productive now because of poor tiles. It can get access to 3 BGs after expanding borders. So i may switch barracks to a library if the situation on the front will be more or less quiet. This is also the city our free settler should join, because it is the only one without a food bonus and the closest one.
Iznik is building Palace and has accumulated 22 shields. I really don't like that build - it takes more then 40 turns to build SoZ and more then 40 turns to get access to wheat and BGs.
Uskudar has some nice tiles, but is very corrupt. It should buil a courthouse quite soon. A courthouse in this case will help more then usual, because most of the corruption is distance corruption, while in a normal game at least halve and usually more is rank corruption. A corthouse cuts distance corruption by halve and only reduces rank corruption slightly. So in case of 5CC it should be much more effective then usual. A library there will give 1 BG, 2 forest and one grass tile. Not very urgent, but still nice to have.
OK, after thinking about this for a while i think that M60's plan is the best. I'll switch Edrine to SoZ and Iznik to a barracks->library and start TGL later in Istanbul. This is the most efficent way: we get SoZ almost 30 turns faster (!), that's 6 more ACs. If AC=knight that's ~400 shields saved. We get TGL at about the same time because Istanbul should be able to build it in 30 turns, maybe even faster if we improve the hills. We won't waste food in Edrine that cannot grow now, but can put it on workers instead and later build an aqueduct. We'll get the good tiles around Iznik earlier. Finally getting ACs earlier will allow us to build libraries instead of units in our other cities. So basicly all our cities will benefit from such a switch

. We'll loose ~30 shields in Edrine because it'll take some time to connect ivory, but i think it is not that important compared to all these benefits.
1000BC, end of NP's turn
- switch Iznik to barracks (if we go straight for library we'll loose shields).
- Continue building the sword in Istanbul. I don't want to start TGL prebuild yet, but do several worker-sword cycles because we might need some troops urgently and the workers may very well speed up the build and regain lost turns.
- Hire scientist in Edrine and lower lux.
- Settler/spear pair start moving.
975BC
- Send 2 workers to hook up ivory ASAP. The new sword from Istanbul will protect the colony.
950BC
- Istanbul builds sword and grows, worker next. Lux raised for a turn.
925BC
- One french warrior commits suicide at Uskudar. (1-0) Mongols are chasing our settelr pair, but have no chance to catch them.
- Istanbul builds worker, starts another sword.
900BC
- Writing is done, Literature is next, due in 13 turns now.
- Mongols stopped chasing our settler pair and they have a stack of 7 archers that can arrive at Uskudar in 3 turns. I sent some reinforcements there.
875BC
- A road from Istanbul to Bursa that doesn't cross river is done.
850BC
- Istanbul: sword->worker, the last one before switching to TGL, i think.
- Iznik: barracks->library prebuild.
- Our sword dies attacking mongol archer, another sword kills mongol archer, our archer kills mongol archer near the iron hill. (3-1)
825BC
- Istanbul: worker->TGL, due in 37 turns now at 11spt, but that would drop drastically after i MM for shields when Istanbul growth. It will take not more then 25 turns.
- The free settler arrives at Bursa, but i change my mind and decide to join it to Iznik, it is currently our smallest city and the wheat tile there is blocked from the river by 2 mines and it won't be able to catch up in growth quickly.
800BC
- The mongol stack attacks Uskudar, we losoe a vet spear and kill 5 archers. (8-2)
775BC
- Bad news: the mongols have another source of iron because i see 2 mongol swords. One of them is now near Uskudar, the other one will arrive next turn. Our sword dies attacking mongol sword. Another sword finishes him off. Our archer kills mongol archer. (10-3)
- Ivory is connected and SoZ will be done next turn.
750BC
- SoZ is built in Edrine. Start barracks there so that it produces veteran ACs, due in 4 turns with a chop, so our first AC should be veteran. After that Edrine should produce some more workers.
- TGL is due in 21 turns in Istanbul currently. We'll loose some shields if someone completes the Pyramids before we learn Literature (7 turns left), but not much.
All recent mongol atatcks were at Uskudar. There is a stack of a sword and 2 archers next to it now, we have a spear, 2 swords (1 of them wounded) and an archer inside and a spear on the iron hill next nearby. I'll leave it to the next player whether to attack with our sword and archer or not. Bursa and Uskudar are building swords currently, but i think at least Bursa should be switched to a lib unless there is an emergency. The free settler is in Iznik and should join the city after the cultural expansion. Alternatively we can wait for it to get to size 7 before joining to save some food.
