This was my first GOTM and I went with the adventurer bonus. SpaceShip victory in 2011 AD, base score 4180 (final score 7266). Usually I play on marathon speed.
The plan was to go for Archery asap in order to handle the raging barbs, but take mining first so I could work the hills, survive until 0 AD and then decide what to shoot for. By the time i got mining, my 2 archers had found the 2 chokepoints.
This got me thinking and I figured I could hold the position and go for BW, hoping for some copper nearby. But no such luck.
Early build order: barracks -> switch to worker at size 2 -> warrior -> finish barracks -> workboat -> settler.
So, by 2680 BC I start producing archers, just after I whipped/chopped my first settler (Washington had reached size 4).
New York is founded in the north and has 1 gold, the pig and horse in its FC. I chose to have 3 hills instead of that second gold in the FC, because I wanted this to be my military production city. This worked out very well, because in the late game New York was producing 10 XP Modern Armor every 2 turns (without Ironworks).
In 1840 BC Stonehenge is built in a far away land, just 2 turns before I would have

. I switch to the Oracle and whip it in 950 BC. I take COL and confucianisme is founded in New York and not Boston. This puzzles me: didn't I read somewhere that a religion is always founded in your last city?
In order to improve my relations with the AI, I trade COL for sailing and IW and give my extra clam to Monty. Shortly ater both Monty (founded judaism) and Biz convert to confucianisme, and so do I.
A quick note on the agressive AI setting and religion: despite every AI founding his own religion and eventually converting to it, the first inter-AI war started in 1450 AD. Yes, that's right, AD, not BC. What's up with that?
At 400 BC, I take a break and do some thinking: my (limited) scouting revealed that Biz is located to the north of me, has copper and is boxed in by a mountain range. Nappy holds the only iron in the area and is expanding rapidly. Monty is located to the south, but we're separated by a sea and mountains. I have 3 cities, no metals and a limited number of resources. I did spot the copper to the south later on, but it didn't matter anymore by then. Did I mention my poor scouting?
A quick note on the raging barbs: where are they?? Up until 0 AD I only saw three (3) of them. My chariot and foritified archers handled them with ease. Maybe my empire was so small at the time, they didn't bother...
Around this time I read a post from A'AbarachAmadan in the final spoier of GOTM10. This mentions the use of horse archers in early warring. Until then I never considered their use in that way. Normally I use axemen/swords to rush the nearest AI.
And so the Grand Strategy will be: build 10 horse archers, take the iron city from Nappy, cripple him in a way he won't bother me for a while, build maces and take out Biz. Now I was thinking about winning this game by Conquest/Domination.
In 25 BC I get my GP from the Oracle-points. A few turns later I take CS and switch to bureaucracy. In 540 AD my army is ready and I declare on Nappy. With only HA I quickly take the iron city and Paris. Then I sue for peace but get only some money for it. I read from other people that they got techs from peace deals. How do they do it? During the entire game none of the AI would ever give me any techs. At one time Biz would even give me a city rather than a tech.
In order to make sure Monty doesn't invade me from over the water, I always keep twice the number of his ships near my capitol.
By 920 AD I have met the other civs and start trading maps. This reveals a lot of land to be conquerred/settled. In the mean time, Biz builds the Pyramids, Chichen Itza and Colossus, while I get GL and GLighthouse. Building the National Epic in Washington screws up my GP-points and I get a GA instead of GS or GP. I beelined for Machinery and my maces are being produced at a nice pace, but just before I want to go after Biz, he upgrades his archers to longbowmen. So it takes me until 1250 AD to gather enough maces+cats to take him on.
All this time, Monty seems pre-occupied with taking barb cities and leaves me alone. In fact, Monty never gives me any trouble. I realized that I just had to keep him busy in order to keep him of my back. So, whenever possible, I gave him a few techs to go after Ghandi or Qin. By the way, Ghandi had been a good trading partner, but became way too tech-savy to my liking: he discovered Liberalism in 1440 AD first and had a good tech lead, until his neighbours started to pick him off.
By the early 1400's Biz is no more to the north of me, but he is still alive. Seems he build himself a galley and settled 2 cities to the north of Nappy, which means I'll have to go through Nappy to get to Biz some time later. I continue the military build up, including knights, and in 1545 AD, just before I want to finish the job, Nappy declares on me! The war started promising, but when I wanted to take his new capitol with my SoD, I hit a brick wall. Well, actually, a longbowman on a hill in a city with CD2. Looking at the power graph, I lost about 25% of my total value. That's how bad it went. By
the time I got my second wave into position, Nappy reinforced the city with 3 longbowmen, 1 cat, 2 maces and a crossbow. After a long and bloody war, I finally took out Nappy and Biz. But I lost all appetite for a Conquest/Domination victory.
The normal speed setting and difficult terrain counteracted my flanking moves (which I love to do).
Instead, I went for a SS. During the 1800's, Ghandi was finished by a combined assault of Monty, Alex and Qin (I might have had something to do with that

). After that, I sent Monty onto Qin and joined the fight to take over the cities Qin had settled near/between my land. This greatly reduced the length of border I had to defend later. Once Qin was defeated, I tried to set Alex upon Monty, but he refused: "we have enough on our hands". Well, you know what that means...
Luckily, by the time Alex declared on me (1937) my tech lead and production capacity (thank you 3GorgesDam) had grown to a level that I could match his cavalry with infantry and cannons with artillery. The rest of the game was all about building SS-parts and keeping up on the power graph. I must say, if Monty and Alex ever had decided to join forces on me, things could have turned ugly. But with the extra modifiers I got from warring with Monty, it didn't happen. I did settle one more city early 1900 to get aluminum, amid Monty's captured barb cities.
In 1992 I used one of my late GP and the GE from fusion to trigger a Golden Age. This allowed for a nice boost to the Space program and helped to get the necessary units (stealth bombers, modern armor)

to take care of the latest attack from Alex (gunships, tanks, artillery).
I didn't bother to build the UN, because Alex and Monty liked each other more than they did me and I thought it could have lost the game that way.
Conclusion: This game felt slow on the tech front. The map was very nice with the mountain ranges and all. I think I need to do some work on my early game. But more so, I need to focus more on my goals. If I want to go for a military victory, I need to apply more resources to that goal and fight the builder habits.
