1260 AD: My golden age is ending this turn, I used the first set of civics during GA, switching to 2nd set for war with Mehmed.
And post-war:
*Note: Free Market was a mistake, I expected to have Astronomy and Oceanic trade available sooner. Organized Religion was "OK" but maybe Theocracy was better.
1380 AD: Declared war on Mehmed! Power ratio of 0.6 to Ottomans.
1400s: The war started slowly, killed a big stack of his (25 units) on the first turn, but didn't gain any key cities for a long time due to spies failing with 88% chance to cause a revolt. Also had few trebuchets.
Tech came to a complete stop after Democracy, Statue of Liberty should finish but I'm not sure if I'll be the first to Communism.
Mehmed should finish Astronomy by 1550 AD, I'll peace him for it when I'm ready.
My 0.6 ratio turned into 2.0 ratio in ~15 turns!
Met the others on 2nd continent!
Mongolia is the master of the Vikings and is plotting war. (Darius is his worst enemy)
1530 AD: Mehmed caps to me and I took his Notre Dame city!
1550 AD: Mongolia, on the verge of dominating Babylon and forcing his way to a 2nd vassal, has Ragnar renounce vassalship!
1580 AD: Uh. OK. Had a bit of a bug. Mongolia asks me to join in his war vs Hammurabi, I join. Hammurabi immediately asks me to join his war vs Vikings, I decline. Then the "We shall remember this." Line comes up, with the option to open trade table. I trade, ask what the price for peace is, he says impossible and the side panels close, but I can still ask him if he will accept this deal (assuming cease fire for nothing) and he accepts. This makes Mehmed also declare war and peace within the same turn.
1595 AD: I was first to Communism (Persia 1T away) and used a Great Engineer on The Kremlin, but still lost it by 1 turn! Damn, man.
Now Babylon is the vassal of the Vikings. Odd power swing, feels like some Game of Thrones backstabbing is going on over in Westeros. Yes, that continent was just officially named Westeros. This must mean I have dragons and wizards somewhere on my continent!!!
1600 AD: I'm slightly behind Darius in tech, the Vikings have the lead in culture but it's currently nothing to worry over (3000+ culture for 3rd city), and after the Vikings eliminated the threat of Mongolia ruling over 2 vassals, if anyone is dominating this game, it's me. Diplomacy is a scare, all of Westeros dislikes me or is cautious of me and the Vikings have a bromance with Mongolia, the 2 powerhouses on their continent. Also the 3 Buddhists are basically a pact now, with the Apostolic palace (Babylon) present I would worry of ever threatening the Vikings to where they may put a vote towards victory on the table.
I believe someone will plot war on Darius soon.
I'm putting all espionage (other than the amount needed to see teching) into Darius so I can steal any techs I fancy.
Maybe I'll war with Infantry + Tanks like I did in my Emperor game for the last NC. Had a close call with diplo and culture victories though.
