I've played six turns and wanted to pause for discussion.
Here's the turn log:
============================
Pre-flight:
We have 139 gold
Do a deal with Alex: Whales for 240 gold (negotiation doesn't seem to work in Civ5)
We now have 2 happy faces
Buy a Worker for 310 gold, leaving 69 gold.
Check the citizens: Working 2 fish, whales, stone and cattle
Hit Next Turn
IBT: Our northern Jag is attacked by barb brute. 6 damage. We are down to 2/10 HP. Barb has 3/10 HP
Turn 31 2760 BC
Wounded northern Jag backs away north to the forest. There's a Russian unit to the east that can attack the barb.
Worker to coastal hill
Southern Jag healing at 8/10 HP. Not sure how he got wounded - no record in the previous turn set.
IBT: AH discovered.
Turn 32 2720 BC
Wounded northern Jag fortifies to heal
Worker starts mine. 6 turns
Southern Jag is at 9/10
Choose Writing. 8 turns
IBT: Russian troop movement. They probably killed the wounded barb last IBT.
Venice and Cape Town are both under barb attack, and ask for assistance.
Border expansion means we now have 2 pearls.
Turn 33 2680 BC
Southern Jag heals. Moves to hill 2 tiles NE. Finds Hanoi border, Dyes, Wine, barb camp, and a barb brute next to the hill. Should have moved one tile at a time! Let's hope we'll win some Brownie points from Venice and Cape Town.
Workboat next turn. Production = 6 hammers per turn, and 6 are needed.
The nearest horses are 5 tiles NE of the capital, past the cattle.
IBT: Genoa comes under attack and requests assistance. Workboat completes. Barb near southern Jag moves east.
Workboat completed.
Turn 34 2640 BC
Send Workboat to southern pearls and make nets. Move citizen from fish to pearls.
We are now on 9 gpt, 6 happy faces.
Select archer as next production (7 turns)
In memory of the mild-mannered Karasu, I decide to attack the barb with the southern Jag. Estimated result is minor victory. Actual result is a draw, both losing 6 HP. But at least I'm still on a hill.
IBT: Jag gets a promotion. Barb moves SE to forest. An Unknown Civ reaches the Classical era.
Turn 35 2600 BC
I can either instant heal the Jag and move, or choose Drill 1 to increase strength and fortify to heal.
I choose instant heal. I then have a forecast of decisive victory against the barb unit. Could win points from the three city states ... or not!
Southern Jag attacks the barb and wins, losing 2 HP.
As he does so, he contacts City State Hanoi. We are the first to meet them, so we get 30 gold.
Traded pearls to Napoleon for 240 gold. I was only trying to find out how much he would pay, but when I hit Propose, the deal was done!
We now have 355 gold, and can afford to buy anything except a settler, and we get a free settler next turn anyway.
IBT: Southern Jag attacked by a barb. Loses 2 HP. Barb dies. That's two. Let's hope we are going to get some credit from the City States.
A Greek archer arrives outside our NE border.
Message from Hanoi. Thanks for the dead barbs, have +12 influence

Pop grows to 6.
Turn 36 2560 BC
We adopt Collective Rule, and a Settler appears outside the capital.
Fortify southern Jag to heal.
+++++++++++++++++++++++++++++++++++++++
It's now Turn 36 - 2560 BC. We just adopted Collective Rule, and we have a free settler, and two 6/10 damaged jags some distance from the capital.
We have enough money to buy a settler escort (archer or jag), or we could use it to buy a workboat to fish the second pearls.
I have not done as much exploring as I would have liked because of barb action (almost none!), so we know no more about the terrain east of Cape Town.
In order to use our settler, we need an escort. We have an archer in progress in the capital with 5 turns to go. This can be reduced to 3 turns if we MM for max. hammers and reduce food to stagnation level for those three turns. Or do we buy an escort archer now, and keep the one under construction for other duties?
And of the two sites under discussion, which do we favour? Or do we hold the settler for a few turns and push our wounded jags into the fog to see what's there?
Lots of questions!
Here's the save.
