i am heading for a science vc this time. won´t tell which one, but one hint: i still miss it in my COTM-record
as i have some serious connection issues at home i can only play offline at my house and post at my office

so i cannot give much of a progress report yet. i think it is around 660ad, my core is finally railed, and i have finished 4-turn research on, i believe, 7 IA techs. not very impressive, i know.

We're close. It sounds like I'm currently ahead, but teching slightly slower, having used up my GA already. I'll keep schtum about whether I'm going space or diplo, and refrain from checking your Pantheon status. Good luck!
Gifting up the SCIs
Entering the medieval in 925bc mainturn, I gift up Theo, who gets Engineering, and X-man for Feudalism. Very good. They don't even know each other yet, so trading for these techs shouldn't be too hard; Republic for Engineering straight up, and then Engineering + Republic for Feudalism. So I set research to Monotheism. After a couple of turns inspecting my borders, the Carthaginian axes I was worried about in the last spoiler head south again. How disappointing, I need a golden age. Well, I'll turn my attention to Persia instead; it's always handy to reduce SCI civs to 1CC vassals who can be milked for free techs. A town I aggressively settled next to Persepolis flips in 825bc, which was expected, but I'll have it back shortly.
The New World
In 690bc, an eastward-bound suicide galley meets the Vikings; I sell Maths for a very welcome 110g. The galley survives and starts circulating clockwise. It finds an Egyptian axe in 430bc and meets Arabia in 390bc, after sailing past out-of-reach Incan borders. Abu has 106g which he gives up for Laws. I don't dabble much in the affairs of this continent for now, but I'll be back after Magnetism to grab some of their luxuries.
A Leisurely War
In 670bc I have enough ACs to make a war against Persia stick. I dow and immediately take Pasargadae, and then sit back for a while, waiting for the right time to take the next town with slavers; I don't want to start my golden age at the end of researching Theology, as it won't give me enough boost to save any turns. Better to start the GA the same turn I start a new tech... 610bc in fact. A leader also pops up pretty soon, and an army of ACs is obviously called for. Defended by only a single spear each, Persia's outlying towns are easy pickings. I stop when he has just Persep and hill-bound Gordium left (okay, actually I accidentally take Gordium, so I have to let him recapture it

, giving me war weariness). I want to take Persep after it has finished its wonder build, and leave X-man stranded in a town that won't grow above size 2. But when will that wonder complete? I let him win an easy immortal/axe fight to get his GA going, but it's still a painful wait. Finally in 30bc, Persia has my wish come true and builds Pyramids. Heroes. I claim the prize in 10ad and give X-man peace. The armies can head for Carthage next. I dow Hanni in 170ad and start trekking south, wishing I had already laid down roads.

Industrial era reached in 190>210ad.
I built both Copernicus (in the capital) and Newton (in the FP town, which is less beaker-rich than the capital, but I really mismanaged my wonder builds).
