The Ancient Age
I used a six-turn combo factory, starting with an impi and an axe per cycle, and moving to a sword per cycle when the iron got hooked. The impi went to patrol the southern part of the peninsula, while the axes were destined for my Iroquois campaign. The Quois, Arabs and Celts were met early on, Alex bought my contact, and I traded contacts to meet the Indians, Romans and Ottomans. Abu dowed early on, which netteed me two towns for no effort, and in 775bc I began my own war against the Quois. Researching Republic allowed me to trade my way into the medieval in 470bc, and I also revolted, drawing 7 turns of anarchy. Both Alex and Osman got Feudalism as their free tech, and I traded it for Republic.
The First Quois Campaign
My swords advance into Niagara, just beyond the choke, and then attempt to move east into Salamanca itself. The rivers in this region hinder movement such that the journey takes several turns, and my units are always distracted by Quois archers heading in the opposite direction. I eventually take the town, it flips a couple of turns later, and I retake it for good in 430bc. I turn my swords south to take the Quois horse towns, and autoraze the town to Salamanca's east; Watha is despotic, and is whipping these towns down to size 1.
End of Anarchy
My gruelling 7 turn anarchy ends in 330bc, and the Republic is inaugurated. I have large unit support costs, and have to start off with a commerce rate of 5.4.1, but this is alleviated when the last two civs are met. They were missing so long I had assumed they were overseas. I had a galley heading that way, and it bumped into a Korean a couple of turns after the Ottomans first met them. They were behind in tech of course, but had a little cash to give me for bringing them into the medieval. Happily, they both got Engineering, and again Republic was sufficient to buy it.
Early Golden Age
I have settled the horses, furs and silks in the grasslands on the other side of the Zulu Gulf, but don't have much military in the area. These towns come under increasing pressure from the Quois as I squeeze them northwards. While using an impi to confuse a Quois archer heading for my horses, I mistakenly kill the enemy unit, and the golden age begins in 270bc. This is rather earlier than I would have liked in a science game. I normally prefer to use it at the start of the industrial, when 4-turn research is often suddenly hard to acheive.
Getting Science Into Gear
With hindsight though, this was probably a good time to get the GA. I got Monotheism in 7 turns plus my anarchy beakers, but I am now comfortably in the 4-turn research zone. I give Watha peace when he is down to two towns between his original core and the Celts, and settle down to get some decent wonders built. Zimbabwe goes for Copernicus - the site is one of the most perfect 20k locations I ever saw, with all that gold and river, and enough shields to hit some important production thresholds. Further upriver, Hlobane starts prebuilding Leonardo.
A Wonderful World
The golden age is spent uneventfully, ending with the completion of Copernicus in 150ad. The next turn, Brennus comes up with Invention. In 190ad I reach Banking though, and have exhausted the potential of the top branch of the tree. There's no point waiting for the AI to get Guns, so I start researching it myself. The Pyramids are finally completed in 250ad, and it is Gandhi who did the deed, which is nice as he is a sensible choice to attack next anyway. The next turn, Greece finally finishes Colossus! Crazy. I could have built that easily by now, I just didn't think of it becasue it is normally gone so early.
Watha Way To Go
Before I start on the Indians, I want to clean up the Quois situation. Watha has switched to Republic, so his towns should get less units and whip weariness now. By 310ad, I have taken the two towns I left him with, but I belatedly notice that he has built another on the bay south of Entremont. It takes a while to trek across the mountains to get there, but it is worth the wait. Taking this town in 360ad gets me a leader who goes back to put the FP in Salamanca. I also use a bit of tech tricking to get the gpt coming in, and leave the AI parked at Chemistry in case someone manages Metallurgy while I do the Physics techs.
Ending the Age
I start my Newton prebuild rather too late - only 2 turns before getting Physics. It shouldn't slow my acquisition of the last medieval techs, but my real worry is that the AI has plenty of prebuilds on the go. Pretty much everyone is doing several wonders, and these builds have been cascading along for hundreds or thousands of years. When I hit the industrial, I will want to bring the scientific guys up with me, but that will mean giving them Gravity, and a cascade could quickly rob me of a key part of my strategy.
Sun Tzu drops to the Arabs in 480ad, but the best builds continue in the form of Michaelangelo and Leonardo. So when in
490ad I learn Metallurgy and enter the industrial, I decide that I can't afford to risk gifting anyone up until Newton is done in 3 turns time. That makes my research choice a bit of a blind one. So I just go for the best tech available - Steam at max.
