A few turns later, Fred has met Ragnar, so he's willing to trade Machinery+Construction to me for Feudalism+Paper. I consider switching to Printing Press, but decide to finish Nationalism. With Marble, I want to try for the Taj. Cathy shows up, and I trade Philo to her for Compass+50+Fair Trade diplo bonus.
1200 AD. PP is done. My research jumps from 256 beakers and -8 gold to 285 beakers and +1 gold (slider at 70%). About a 15% jump. Not a bad tech. Ragnar got Liberalism a few turns ago, choosing Astro. I sink two turns into Ed, at which point Cathy will trade it to me for PP. The next turn I trade Ed to Brennus for Engineering+Optics, and to Fred for Guilds. Note that, with Engineering+Iron, I can no longer build warriors (they're pikemen instead); but I've still avoided HBR, so chariots are still available as relatively cheap garrison troops. I still have the Nationalism monopoly, that I know of.
1240 AD. Taj. Ragnar is in WFYABTA. Screw him. Trade Nationalism to Cathy for Liberalism+110. Constitution finishes. Brennus demands Liberalism, which I grant. Augustus arrives. I gift PP to him, bringing him up to cautious, then get Gunpowder in trade for Education.
Constitution is a monopoly. In addition, I have Nationalism over Ragnar and Augustus, and multiple techs over Fred and Brennus. I think that means I'm ahead in the tech race, though it's not yet a "clear lead".
Wang shows up in 1320, just as the Golden Age is ending. I gift PP to him, leaving me only Constitution, but he doesn't have anything new. I'd like Banking, but I'm not convinced I should trade for it, at the cost of the WFY demerit. It's only a 2-3 turn tech. I think I can afford to wait.
Units so far: 7 settlers, 8 workers, 2 workboats, 40 warriors, 1 chariot.
Buildings so far: 8 granaries, 8 libraries, 7 courthouses, 5 mints, 3 lighthouses, 3 harbors, 3 aqueducts, 3 barracks, 2 monuments, 1 university. With a lot more universities under contruction. My cities are all in the 8-14 size range, necessitating the health buildings.
1360 AD. Democracy. Switch to Emancipation and Free Religion. Research Banking-Econ, I think. Astro is the other possibility. Oversees trade routes and resource sales can be very profitable. Cities are pretty much maxed out by food at this point.
1400 AD. Econ. Switch to Free Market + Free Speech. I'd like switch to US at some point, but only if I can scrape together enough other sources of happiness. Corporation next, then trade Econ+Nationalism to Fred for Astronomy. Sell spare Silk and Wheat for cash. Sell my world map, and I can run at 100% for several turns. My GNP is the highest, and rising. Chemistry in three turns, for example, then Steam Power in five.
1540 AD. Cathy, pleased, declares. Yeah, she's like that. 4 knights and 2 trebs. I upgrade some warriors to pikes and fight her off. She's had Chemistry for a while, so I expect that the next wave will be grens. But I'm only two turns from Assembly Line.
There is no second wave, and she agrees to peace for Steam Power. Right back to pleased, she's even willing to sign a defensive pact. Crazy woman. I tech through Steel to Railroad, then trade for Scientific Method, Physics, Biology, and research Artillery, Rocketry by 1665 AD. Start the Apollo Program in my best production city, which isn't very good. I haven't even started Ironworks -- need one more mint first. Space races are usually research-limited rather than production-limited, but this may be the rare exception. Timbuktu is running as many engineers as possible, in the hopes of GEs for the Space Elevator.
Detour to Medicine. It's a dead-end tech, but with factories and coal plants coming online, I'm facing unhealthiness. I'm able to trade it to Cathy for Combustion+610. I'm 2+ techs ahead of everyone. Radio, then Computers in 1770 AD. I've been selling old techs for whatever I can get to keep research high. Biology for 250, for example. Do I really care if Brennus has Biology? Maybe he'll even research Ecology for me. I try to avoid trading like this to the nearest competitors, however (Cathy at the moment).
1800 AD. Industrialism, for Aluminum. I join Ragnar and Cathy in a false war against Wang. But then he begs the protection of Augustus (who already has Brennus as a vassal) and suddenly six new wars are declared. Well, hopefully Augustus/Brennus/Wang will have their hands full at home, but I build some tanks and artillery just in case. Indeed there's no invasion, but he does send destroyers to trash my fishing fleet. I'm forced into Environmentalism for the health benefit. Wow, it's been a while since I ran Environmentalism. Eventually I buy peace. Meanwhile I've teched Sattelites and Fission. Trade Fission+Computers to Cathy for Plastics+war vs. Ragnar. Keep 'em busy. Fusion, then Robotics. I rush the Space Elevator with two GEs that I've saved, finishing it in 1876. No one is seriously competing with me for space parts. Refridgeration, Genetics, and Ecology last, finishing in 1888.
Launch in 1914 AD. Fred was the next closest, lacking Sattelites, Fiber Optics, and Fusion, plus the construction time for parts. Very comfortable.
Summary: Isolated starts on Emperor are nothing to be afraid of, as long as you have reasonable land and know what you're doing. HR and cheap garrison troops for happiness, cottages and more cottages, get to Democracy and Liberalism for the good civics, diplomacy and trading, win.
