haha, okay. i'm not used to founding cities just to give them away.
played to turn 50.
got my 3 hilltop cities. AH reveals Horses 3N2W. Ragnar is plotting. The Mongolians are lower on score, and to the North, so maybe they have some bad tundra land. Mongolians don't seem to have copper, as I only see archery units. Same with Tok. I opened borders with Rag, and he has some axes in Haithabu. The bad news is that Ragnar, Ghengis and Tokogawa are all buddies. The good news is that Ghengis and Tok are worst enemy of Ramses. Bad news is Ragnas is plotting, and he feels the same about me and Ramses.
...was hoping that I'd get a fgn trade route with OB with Ghengis, but none of his cities are connected to the river.
No trade route with Genghis on river without Sailing, sorry.
Good work getting Open Borders with Genghis and Ragnar as fast as possible and scouting Ragnar with a Warrior.
Ragnar plotting war is concerning.
He won't target another warmonger usually since they are all Pleased with each other.
I'd give
40% odds he is targeting you (your power ratio is much lower than others), 30% Justinian, and 30% Egypt.
If you see 5 Axes heading in your general direction, get 5 Archers onto hilltop
Boston as fast as possible.
The Archers will have 6

freshly produced, 6.75

when fortified for 5 turns, and 7.5

if Ragnar attacks fortified Archers from across the river.
It should be able to win against 5.5

Axes.
The DOW won't occur until the enemy stack steps into your borders.
Your capital is going to pop borders next turn, so there is a good chance you can steal those Pigs from Tokugawa
for a few turns until he pops borders in his mystery city.
I wish you could see if it has Hinduism in it (or a Monument if you zoom in and squint), but you can't.

Placing a city there to take advantage of the pigs is a gamble that probably isn't worth it.
Sharing a long border with Toku will just infuriate him.
Currently, if he attacks it will probably be against your capital, and the +40% cultural defenses means he won't have a chance if he uses mainly Chariots.
Roads to connect your 3 cities means
5 or 6 Archers can move to whichever city is under attack.
Roads will also give you trade routes when connected to neighbor civs (
isolated capital hurts!), and religion spreads will start to happen which might change your diplo situation to not so deadly.
So I'd recommend
Archery, then tech The Wheel for Roads and Chariots?
Try to make
1 or 2 Chariots before Genghis' culture pressure takes your Horses away until you get Libraries.
Rivers connect cities inside your borders without Sailing, so road Horses to connect 2 of your cities to each other.
Road Cows or 1E of capital to connect to river which will connect to your other cities.
Road north or northwest of Horses to connect to one of Genghis' roads to get trade routes.
Road to Tokugawa's pigs to be able to trade resources with him and maybe get Hindu spread.
Don't road to Ragnar until you are sure he is targeting someone else.
The maintenance on Deity is too high to support too many units with only 3 cities ugh.
Might have to delete your Warriors when the good units get produced to be able to keep teching?
Deity only supports 5 units, so that means only the 2 Workers and 3 Warriors are free.
Every unit past that is -1

per turn until your cities get larger population and supports more units for free.
Ragnar only trades strategic resources when Friendly, so he won't be trading away any 2nd Coppers he acquires for Elephants + Horses.
Later on, Libraries and Scientists making Great Scientists for Math/Alphabet/Philosophy will keep you in the tech game until you can get Horse Archers and start fighting back a little.
You won't be able to really push back until War Elephants and Catapults.
