Awesome write-up, @Kaitzilla
I got a couple of remarks/questions :

Not sure if it's worth it to wait for Construction, it's probably better to go all-out with Axes right now. A shame that GK got walls so early. Grinding him down without siege will take some time, but going for Construction would take ages and you'd have to fight a defensive war in the meantime anyway. After you're done with him, recovery will be easy as you're financial. (Assuming that you can keep JC off your butt).
Anyways, I'll be watching, good luck!
Btw @Lain good job on the Sury map, what you had to go through in the early game would've made me rage-quit a dozen times
I got a couple of remarks/questions :
Spoiler :
- Going for Pottery this early, did you ever work the lake tile?
- The AI can't plot war with just chariots (needs 2 units strictly better than the Archer), so you were safe until GK got metal or HBR
- IIRC, barbs only start entering borders when the average number of player cities is superior to three, so basically when every AI in the world has 3 cities and some start settling their 4th one (because you won't have 3 cities at this point anyway)
-
Boom, stole the Wheat.
This caused -3 Border Tensions diplo the following turn 65 when the Land Target kicked in.
