The Ancient and Medieval Ages
I used Zimbabwe to produce 6-turn settler combos, mostly filling the zulu peninsula, and also expanding east across the gulf to grab the handy horses and luxuries over there. Although the Arabs dowed me early, my first real war was swords into the Quois at the end of the ancient age. I reached the medieval in 470bc, with 7 turns of anarchy before the republic was ready. Trading Republic for scientific free techs got me Engineering and Feudalism, and I researched my way up the top of the medieval tech tree. An impi-initiated golden age kept research speed high, and in republic, Zimbabwe was refitted into a science powerhouse, using the gold and building Copernicus. The AI helped my research to the tune of Invention, but apart from that I had to research the lower branch too. I finished the Quois off towards the end of the medieval, and in the final siege I earned a leader who put the FP in Salamanca.
Free Tech Bonanza
I reach the industrial in 490ad, and much as I would like to gift the scientific civs up, I dare not, for there are many long-standing wonder builds going on, and I can't risk not having Newton in Zimbabwe. My build is due to finish in 3 turns, so I set full research to Steam for a couple of turns, and only in 510ad do I start dishing out the knowledge. Osman gets Steam, and the other three get Medicine. I have to wait another turn before I can afford to buy Steam - it costs me 1710g, but I can use it to get Medicine, and then sell that to Osman to get 1230g back again. Well, that's all the help I can expect in this age. I start researching Sanitation, as I want to grow Zimbabwe large enough to work 20 tiles.
No More AI Wonders
In 540ad, Greece completes Michaelangelo, and all the other AI have to queue up their best builds on Leonardo... but Hlobane will have it 1 turn :sumg:. My Sanitation research is done in 4 turns; Zimbabwe immediately throws up a prebuilt hospital and pops to size 18. With full railroads and a couple more citizens it will do 50spt net of corruption. There's no reason now why I should miss another wonder. After Sanitation, I head straight for Replaceables. I could leave the AI on Electricity while I do the Corporation branch, but I can't guarantee they wouldn't still waste their time doing government techs, and I need the extra worker power quickly. There is so much land to improve, and jungles to clear, and I currently have nowhere near enough shovels.
Military Superpower
Parts arrives in 660ad, and I start off down the Industry/Corporation brach. I have 2 cannon, which I upgrade during the interturn, and then send off to attack India. It is time to continue my eastwards expansion, and take control of the Pyramids. I see a couple of jumbos, but they are easily dealt with by my mighty army... in 740ad I check my military strength, and find I am strong to everyone except Greece and Rome (both average)

. My military consists of only 7 cavs, 5 impi, 4 guerilla, 3 swords and 2 arts. By 760ad I am done with India, and I use tech trick to sell the AI up to Industry. I leave the Celts and Arabs out of the deal as I will be annexing these lands next.
Not Scientific? Too bad...
Arabia never really recovered from gifting me two core towns after our cold war in the ancient age. I dow Abu 800ad, and by 820ad the Arabs are reduced to a junk town north of Greece. I let my handful of units rest up a little before they turn north. Brennus gets his dow in 850ad, and also puts up no real fight. The Celts are gone in 880ad, and I have to decide whether to go into Rome as well. If I do, I will be able to reach the last Arabian town, and killing either of those civs will enable me to tech trick again; I didn't do it with the Celts because the AI are still sweating gpt after the death of the Indians.
The Eastern Limit
So it comes to pass that I dow Julius in 970ad. His empire is fairly spread out, but I have a couple of cavalry armies by now, and even a couple of tanks towards the end of the campaign. Rome is gone in 1030ad, and I actually don't bother selling techs, as I have just started my last industrial tech, so the game will end shortly. The Roman lands will be my final eastern province. I take the remaining Arab town in 1050ad, but gift it to Alex for the sake of neatness, and to pump his pop up a little. I want to be sure I know who my UN rival will be... I get up-to-date maps and count the AI's citizens. As expected, Greece has the most (122 to Korea's 91). Everyone seems to have an even spread of city sizes, so I would guess that Greece's population statistic is comfortably ahead of Korea's.
The Price of Fission
I reach the modern era in 1060ad, and each of the scientific AI gets a different free tech! That isn't good, as I am only interested in one of them, and this way I can't even afford a non-monopoly tech to use in trading. I have been stockpiling cash to buy Fission outright, as my per-turn rep is too badly damaged, from tech tricking and some early barb-broken lux trades, to buy it on credit. I have about 15000g, but it isn't nearly enough for Alex to part with Fission. I decide to spend 12000g getting Rockets from Osman, as he is short of a couple of industrial optionals too, but Rockets and 3000g is of no interest to Alex. I am out of options, so I sabotage my UN prebuild a bit and let the interturn end. Happily, the AI trade merrily between themselves in their own interturns, and I can now afford to buy the non-monopoly Fission from Wang, in exchange for Rockets and Sanitation.
Vote Rigging
Now I just need to ally the northern guys against Alex, but I realise I have per-turn deals with him. How sloppy of me! So far I haven't actually broken a deal up front, and I'm afraid my 'supporters' will consider it one abuse too many. I have some cash left, so I try to get Alex to dow me by driving him furious and pulling a careless tech steal, but I just end up with peace and Computers

. Oh well, in for a penny in for a pound. I buy his cash for massive gpt, and dow him straight. The other guys don't seem to mind my misbehaviour, and give me MPPs and alliances against Greece at no great cost. In
1070ad I complete UN in Salamanca, and win the vote 4:1.
