Great game Vadalaz. He now tempted to retire mine, and try 4 cities tradition immediately. Did you get any free techs? How early did you start the conquest?
EDIT: he that's some sick science that you have going at t165. Do post a write up please.
Well, I did have 3 cities build research there, plus a bit of jungle and some trading posts. I think I had banks up in all cities for the extra specialist slot, and the two observatories obviously helped too. Here's what I remember about the game:
The starting location had a mountain, a river, gems, 2 wheat and 2 salt tiles and a lot of trash like tundra and snow surrounding the awesomeness. I settled on gems and my build order was something like Scout x2 - [rush buy third Scout] - Settler - Warrior (had like 3 barb camps near the cap) - Settler - [rush buy third Settler] - Worker x2 - Granary - Library - NC. I DoWed Theodora early because she had some decent cash and sold her my gems so that I could buy a Settler. Had my 4 cities up by turn 42 or so I think, sitting at 9 unhappiness temporarily. I quickly got a mercantile CS ally though, and happiness hasn't been a problem ever since.
Expos BO was Library - Granary - Chariots Archers. The goal was to get two armies, 3 chariots, a Siege tower and a support melee unit in each. I think I finished NC on turn 72ish, then got two Siege towers out of my capital, so I had both armies up by t80 or so. That was too late to have a chance of stealing Drama, but I did get Construction and Engineering from Pedro, who I believe was going for the Great Wall. The extra caravan from Engineering was certainly helpful, my capital didn't have many food tiles except the wheat and salt. Built HG there after the Siege Towers, and got ToA and Petra in expos.
Meanwhile I finished Tradition somewhere around t77, got my religion, which was +100g on conversion/+15% production, built Borobudur just before getting Education and enhanced with +2 faith from wonders to ensure a faith-bought GS and +30% range.
I got Education on t105 I think, with enough cash for two universities. I bought them in the two cities that didn't have a garden, so that they'd get a head start in GS generation. Hard-built the unis in my capital and the last expo. Next stop was Astronomy, as I had two mountain cities. I burned a GW and built the Oracle for a t117ish Secularism. Tried to grab Parthenon as well but Ahmad beat me to it.
Around t130 I had the option to get PP immediately, but napkin math showed that reaching Atomic in time would be a close call then. I wasn't sure I'd get all the GSs in time, or that my average bpt would be high enough etc. Losing by 1 turn sucks and that happens often when I risk it, so I played it safe this time and delayed to t135.
With a bit of GS management (cities without bonuses to GP generation go first) I did get all the 5 natural GSs out in time though, and bpt was fine as well. That plus LToP and PT meant I needed neither Rationalism finisher nor the faith-bought GS to get to Atomic in time. I used 2 GS to get Sci Theory in 3 or 4 turns after PP, then another one for Radio and the rest in the end, plus Oxford for Atomic Theory.
