Preturn: Babylon has 5 cities left including their Capitol. Hit space for the Archers.
Builds look good but slow the Prebuild a bit now rather than waiting.
IBT: Four Persian Archers spotted. The Persians may be just past the Babylons.
330 BC: Science to 50% and break even.
Ignore Persia for now and move next to Babylon.
Army heals.
IBT: Zulu have a Chariot.
310 BC: Capture Babylon losing an Archer and Elite Sword. and build Erdenet. Capture a worker in Babylon. This momentarily solves our money problems and we can go back to 70% science. Start two Settlers. I think we want to get some more cities down quickly before the limit gets reached. 3 Babylon borders are spotted North and West of Babylon.
IBT: FP can now be built. I start it in Ulaan but hope to use it as a Statue of Zeus prebuild.
290 BC: Occupy Babylon. Army will go after other Babylonian cities.
IBT: Babylon settles a new city to the south.
270 BC: Ocean or big lake is south of us. I suspect cities to the south will be 'behind the lines'.
250 BC: Army moves next to Uruk. It is a size 1 Desert town. 3 Persian Archers are near Babylon but no two are stacked. I kill 2 as we end up on hills to help the Swords if attacked back.
230 BC: Kill two Spear in Uruk destroying the city. As surmised a Perisan border is farther west. Also it appears Sumeria has units west as well. Lose Archer to Warrior which we then kill
IBT: Kill attacking Babylon Bowman. Still no Bowmen wins.
210 BC: Army Heals. Lose another Archer to Warrior.
I started the Heroic Epic.
190 BC: Army moves toward Persia.
170 BC: Celts Spotted with 17 cities including Capitol. They have Writing. Declare War. Unfortunately they are south-east. Army takes a LOT of damage fighting a stupid Archer and needs to heal again. Move next to the Babylon city with the Spice.
150 BC: Capture Ashur and we gain Spice. Army Heals. Settle Another town.
Notes:
We have 2 settlers in the spots I was considering Settling. That would put us at 20 cities.
We have fought the Persians and Babylons most heavily, the Zulu have mostly been their UU and only 2 Archers from Sumeria. Sumeria is the only civ with an 'average' military. We are strong to everyone else.
We also now have 3 Lux and can be size 6 with one MP.
I was a bit tired when I played. You may want to check out the builds and such - there may be better ideas.
