EDIT: Well my Ancient Age post got lost so you'll have to make due with my
Middle Age post.
At the end of the Middle Age I was about to complete Copernicus in 1 turn and Newton's in 3 turns. I had gotten Medicine as my free tech and was researching Steam Power at 100% science. Even at 100% it was going to take me 5 turns though. After Copernicus was built I still couldn't get it down to 4, but when Newton's triggered my Golden Age it easily shaved the turn off.
I really wasn't expecting my Golden Age from Newton's. Truthfully I had completely forgotten that I hadn't had a Golden Age yet. It's very rare for me to get them so late in the game. I was planning to research Sanitation on my own to make sure I could do 4 turns per tech in the Industrial Age, but now that I had my Golden Age I decided I could do 4 turns per tech without hospitals and I would let the AI research Sanitation for me.
I gifted Steam Power to all the AI's after learning it. Unfortunately Rome, Spain, and Carthage didn't have any coal. I had 3 sources but 1 wasn't connected yet. I made sure to trade my extra Coal to Rome as soon as possible since they were the research superpower in this game. Now I knew the AI's were all wasting their time researching Nationalism now since they love that tech. My plan was to trade for it as soon as they get it so I could trade it to all the other AI's and make them stop researching it.
I researched Electricity@4, then Scientific Method@4 so I'd have techs to trade for Nationalism. Rome learned Nationalism first (surprise surprise) but I couldn't trade for it without giving away massive amounts of gpt. I needed to research a tech down the other branch so I had two to trade. Btw I had gifted Electricity around already since that would force the AI's to go for Replaceable Parts instead of Communism. Meanwhile I researched Industrialization@4. Carthage also learned Nationalism which made it a lot easier to trade for it without using gpt. I traded Industrialization along with around 3000 gold to Rome for Nationalism, then I traded them Scientific Method to get my 3000 gold back. I sold all techs to all AI's for as much up front cash as I could get and swiped Music Theory at the same time.
I then researched The Corporation@4. I completed Theory of Evolution at the same time I learned The Corporation and took Atomic Theory and Electronics as my free techs. Now I studied the tech tree and tried to figure out what other tech the AI might be tempted to go for in the Industrial Age. I really wasn't expecting to get another tech since I knew they'd go for Communism but I figured I might as well try. I figured Radio and Flight would be the most likely choices for the AI since they had worker improvements and city improvements. Flight would be better since it had units as well but it would be a while before I reached the requisite techs for Flight. Therefore I traded Atomic Theory and Electronics to all the AI's hoping one of them would go for Radio for me. I hadn't finished Hoover's yet but it was due in 4 so I wasn't worried.
I started researching Refining@4. When it was due in 2 turns I turned down research to 60% to save money, even though I knew my Golden Age would end the next turn. Well, I didn't realize my mistake until the next turn when Refining stayed at 2 turns and even moving the slider to 100%, and changing all city configs to work ocean/lakes/rivers I couldn't manage to get it in 1 anymore. So I learned Refining@5. Meanwhile Rome got Replaceable Parts for me (was anyone else capable of researching?) and I traded them Refining for it. I traded Refining and Replaceable Parts around to all the AI's as well so they wouldn't research them.
Now my Golden Age was over but I was still able to continue learning techs in 4 turns, except by raising the slider much higher. I decided I'd continue to wait for Sanitation which hadn't come in yet. I researched Steel@4. I didn't trade it to the AI's because I didn't want them researching Combustion. I knew they'd research Radio before Steel since Steel is a useless tech. I learned Combustion@4 with the slider at 100% and a 200gpt defecit, but I had 7000 gold saved from my Golden Age so all was good still. Rome learned Communism now but I didn't trade for it quite yet because I wanted them to start on Radio. I learned Mass Production@4 and then I traded it around to everyone getting Communism in the process.
I moved on to Motorized Transportation@4. And low and behold Rome discovers Radio! I really wasn't expecting that and was very happy. I traded for it and only had Flight left to go in the Industrial Age. I barely managed to research Flight@4 by leaving the slider at 100% all 4 turns and also micromanaging cities to work water tiles. The commercial docks were just so important in this game. They vastly improve research since coastal tiles produce 4 commerce with a commercial dock.
So I entered the Modern Age in 1000AD. Now I wanted Fission, Computers or Rocketry for my free tech so of course I got Ecology. The AI's
still hadn't researched Sanitation for me and none of the Modern Age techs were attainable in 4 turns. So I had a tough decision to make. Would researching Sanitation myself now save me 4 turns down the road? I decided it would since both Fission and Computers would take 6 turns, while Rocketry would have taken 5.
So I researched Sanitation@4 and low and behold the AI gets it on the same turn.

So I just wasted 4 more turns. I quickly built hospitals in all my cities and started joining workers to the important ones. I figured I'd let the AI research Fission or Rocketry for me since they usually like those techs. Then maybe I could get Space Flight after that. So I researched Computers@5. I started building Research Labs in all my cities that already had hospitals. I researched Synthetic Fibers@5. The AI still hadn't learned Fission or Rocketry even though we'd been in the Modern Age for 14 turns now grr. So I had no choice but to research Rocketry myself in 4. The AI still hadn't gotten Fission so I went on to Space Flight in 4.
Ok this isn't funny anymore. The AI still hasn't gotten Fission, they haven't learned a single tech other than Sanitation and Democracy in 22 turns. I don't know what they're researching that's more appealing than Fission. So I was forced to research Satellites next in 4. After that I'd be forced to learn Fission myself if the AI didn't get it. Thankfully they finally did get it when I was halfway through Satellites. I traded for it and started on Superconductor in 4. I knew there'd be no more help from the AI's from here on. I learned Nuclear Power in 4 and then The Laser in 4.
I used the Big Picture to launch my ship in 1315AD with a score of 5619. Very low score since I never had time to expand after conquering the Celts. Jason score is 8396. I was still very happy with my launch though. It was the earliest launch date for me by 350 or so years.
I also finished the UN on the same turn. I signed MPP's and RoP's the turn before. All remaining AI's were gracious with me. After launching I reloaded and held the vote and won 4-1. Only Rome voted for themselves. India had been knocked off during the Industrial-Modern Age and I took out the Celts myself. That's probably why the other continent sucked at research since they were constantly at war.
What could I have done to improve my score/date? Well I wasted 4 turns researching Sanitation and 1 turn from my Refining blunder. So if not for those I could have launched in 1290AD. Next time I will probably research Sanitation myself at the beginning of the Industrial Age, Golden Age or no Golden Age. I really didn't expect the AI's to take until the Modern Age to get it.
But what hurt my game the most was not having Literature until after I was already in the Middle Age. I think that was just a stroke of bad luck by me that Carthage, Rome, and the Celts never bothered with it. Of course another mistake was even though I researched Map Making early I never built a galley. If I had contacted the other continent right away I could have traded for Literature and probably other techs as well. I think if I had gotten Literature when I expected to get it I would have shaved a good 20 turns off my launch date.
Another thing I'll probably do next time is leave 2 or 3 civ's way behind in tech so I can roll them over at some point and increase my score. Rome was the only civ that researched required techs for me this game. Carthage got democracy and a couple other free techs. I should have just left the other continent in the dust and I could have run them over even with my puny military.
I also would have scored higher if I had gone with a Diplomatic victory instead of a Spaceship victory. The AI really wasn't any help with research in the Modern Age. I could have won with a UN vote in 1050AD if I wanted to. This would have given me an in game score of 6576 and a Jason score of 9185. Nearly 1000 points higher than my Space victory.
I really didn't have any pictures that I thought were worth posting. My empire was unchanged since the Middle Age pretty much. But I know it's hard to keep your attention without pictures. So if you're reading this part of my post then thanks for reading and give yourself a pat on the back for having a good attention span.
