IT- If our trade route to Otto gets broken, we will take a rep hit, having taken 150g from him. Give Spain 120g for peace and we have finally escaped the dogpile.

No need to risk another dogpile over such a relatively trivial sum. Well, the original 8g was even more trivial, but let's at least learn to keep our income positive when we are nearly broke in the future, just in case.
Looks like we have lost our war happiness and now require a raise in luxury tax, or....
Wines plus 1gpt to Spain for Silks and Furs.
Copernicus' Observatory is being constructed by Ottomans, Hittites, and Aztecs, so that means Astronomy is out there (meaning trade routes can go through sea squares). Hittite route is totally safe, as is Russian. Portuguese cities threaten the Aztec route and Russian cities the Ottoman route. This means we cannot declare war on Russia until our Ottoman deal expires.
Aztecs get Horses for Spices and 18gpt, which shouldn't dent her treasury which already has 10293 gold in it!
Russia then gets our only Iron and 1gpt for Polytheism and Construction (since we will be building horses for our future war with her) and we are now into the Medieval Age. All the other Civs are up 6 visible techs, including optional Literature, Monarchy, and Republic (which we'll have in 10 turns), but for some reason the Mongols are back with us, only up Literature, Monarchy, and Monotheism. Wines and all our gpt (57) are close to getting Engineering from the Hittites, but we'll just have to wait.
Slight mm change at Amsterdam to try to get a horseman with growth in 2 turns. Scientist is now at Bolu, can't remember where he was before.
Finally hit enter...
130BC (1): Eindhoven Horseman => Horseman.
IT- Ottomans build Copernicus in Edrine. Ottomans have both the Statue of Zeus and the Knights Templar along with Sistine and Sun Tzu? Uh, look out Cathy.
110BC (2): Establish embassy in Moscow for 55 gold. Moscow is size 7 with 0 growth, making 15spt, protected by 2 pikes and 9(!) spears, along with an archer and 'pult. Russia has 4 luxuries, is running 60% tax and 40% science and Moscow has all possible improvements. A university is due in 1.
Establish embassy in Hattusas (Hittites) for 65 gold, size 11 making 5fpt and 16spt. It is protected by 7 pikes and has all improvements. Hittites have 2 luxuries and are running 70% tax and 30% science.
Establish embassy in Lisbon for 47 gold. Lisbon is size 3, making 2fpt and 7spt. It is protected by 4 shields and a 'pult, with a settler and curragh inside. Portugal has no iron and only 2 luxuries and Lisbon is missing some infrastructure. Portugal is running 70% tax and 30% science.
AI wars we can see:
Hittites-Ottomans
Portuguese-Mongols
Aztecs-Ottomans
AI alliances we can see:
Portugal-Ottoman vs. Mongol
Aztec-Hittites vs. Ottoman
MM Rotterdam for an extra shield and Amsterdam for an extra food.
IT- JS Bach is being built around the world.
90BC (3): Notice the GPT bug in effect. Well, at least the AI is benefiting from it too, so it's not really an exploit. Arnhem Spear => Spear. Utrecht Horseman => Horseman. Found Den Helder in the southern most ruins because it will have more good tiles to work initially. Starts temple, vetoable. Amsterdam is MM to a horseman every 2 turns, with the Hague helping out.
70BC (4): Gronigen Barracks => Spearman (vetoable). Osman establishes an embassy in our capital.
Build an embassy in Madrid, size 12, making 7spt way over irrigated. Madrid is protected by 6 pikes along with 2 'pults and has most infrastructure. Spanish have 5 luxuries and are 60/40 tax/sci. I don't waste my money on the final embassy because we can ascertain the Mongolian status from the rest of the embassies. Spain is at peace with all.
IT- Russia and Aztecs sign alliance vs Ottomans, but trade route to Ottomans is still in tact somehow.
50BC(5): Nothing much.
IT- Hittite Knights ride in the north. Portugal and Ottomans sign alliance vs Aztecs and vs Hittites.
30BC (6): The Hague Market => Aqueduct.
10BC (7): The Hague Settler => Settler. Amsterdam continues to pump out horsemen. Russia tries to bring a settler/spear pain into our land but I block them with horses. Two cities have been founded in the north, one each by Portugal and the Aztecs. Wines deal expires with Russia, and I wait to extend it until we get Republic, to see what kind of deals I can leverage.
IT- Settler/spear pair turns back. Ottomans finish JS Bach in Istanbul.
10AD (8): Scientist switches to Haarlem, who requires a scientist to be happy until we can get a road to it.
IT- Portugal demands wines and I think long and hard about it before teling him to stick it. He is already involved in a bunch of wars and doesn't have time to deal with a small fry like us. Thankfully he agrees.
30AD (9): MM Rotterdam for growth. Getting ready for next turn which will be a big one.
IT- Spain and Ottomans sign alliance vs. Aztecs.
50AD (10): Republic comes in from min sci. Start Feudalism for now. Arnhem Spearman => Market. Found Harlingen in the north, filling in space. Not exactly a great spot, but there aren't many left here.
SO UNFAIR. Somehow the Mongols have developed the Republic, Engineering, and Feudalism in the last turn, with no treasury or resources to trade and no alliances made. This is a major bummer and leaves us with no trade opportunities. I was hoping to catch us up by at least 3 techs here.
Pissed off, I'll pass off here. Amsterdam should build the Horseman with growth next turn, and switching to Republic should help us big time.
Conclusion- Well, at least we have a big treasury and the AI is fighting. And no one is in the Industrial Age yet.
