Preturn:
Look over the situation, and trade for Berlin's map. An assault on Berlin definitely seems acchievable.
Switch capitol to MDI. We chose Monarchy which means we want to engage in wars which means we should always build units, and not wealth.
Raise lux to 10% and switch away from Colloseums where we won't lose shields. I have never considered colloseums worth while.
IBT: Ordered to leave Australia. Not sure our settlers will be able to get far.
710 AD Build on the Iron and the Island
IBT: Single Zulu shows up - Impi
Iroquois declare war. Tes is attacked.
720 AD: Kill the Zulu.
IBT: Russia demanded our Silks. I tried to find a trade for them, but the only one was Russia willing to pay 3 gold for them. Instead we gave them for free. Our plan depends on us not at war with Russia.
730 AD: Zzzz
740 AD: Units are now all at Hovd for next turn.
750 AD: Get Embassy with Egypt, Persia, Russia so we can make ROP deals. Make the first deal with Egypt and move into their territory.
IBT: Iroquois try to sink our curragh, we win. Tes (mongol) falls to Babylon.
760 AD: Can only move 2 due to other units. Send 2 armies ahead to try to grab key tiles to move onto - and one to guard the stack.
IBT: Rampaging Germans destroy the final Mongol city.
770 AD: We are forced off road as some Egyptian troops are fortified. Hopefully this won't happen too many times.
IBT: Magellan is now being built by several civs. Oddly Australia is doing very well in tech being one of the first.
780 AD: Our two galley with Settlers get to the end of Indonesia and find no empty islands. They start heading back.
Some Curragh that are otherwise useless because everything is explored will try to cross to find islands.
790 AD: We got Engineering. I lower our science to minimum. We will get the techs from GLib and if that somehow fails, we can buy instead of self research. Songhai has Monotheism and not Engineering. If we get a enough cash, I will do the trade (again in case we fail). If Songhai gets Eng first, I will just keep the cash.
IBT: An absurd war: Egypt and India vs Australia. Cross water wars never work for the AI. Iroquois also gets pulled in.
800 AD: Do the deal for Monotheism and start min research on Theology. I picked this because if our plan fails we will want to buy Chivalry first and then go for Cavalry. We will never buy Theology, so it has the most chance of 50 turns. Hopefully though, it won't matter which I choose.
Notes:
The forces are off and walking. Likely the AI will be in the next era before we get there.
We do not yet have an ROP with Russia.
I tried to draw a path but there appears to be no 'shortest' route path. I marked one decent path so far. We have to go under Saint Petersburg so we need to stay fairly South. Once we get as far as I marked on the map, buy Russia's territory map again to see what is best.
