What a nightmare o_O
I never play (OK, very very rarely) Vanilla, but the start looked so promising.... I suppose immortal on Vanilla = Deity BtS, right?
As soon as border popped, I noticed small island south, so it was sure to go GLH. But I didnt know, treades will be the same as on main land

I was very very angry, because it was my 3rd city and was left without food at all, not bringing any additional commerce I expected.
My 2nd city went west, 1S from Sheep, so I could start workboat using capitol mine, so my exploration seems quite good.
I know the whole shore of southern island, and have OB with all AIs I met. But of course no benefit, becuse of barb city, also with southern continent.
Happiness and health is madness. I didnt expected I will turn unlucky leaving capitol with no defence at size 4. Now I know that on Vanilla civ there is no charismatic Nap. At least iIndustrious helped with GLH. (giving +2 commerce per city -_- , great).
Then came the worst: endless horde of barbs from the east (west I had fogbusted). And of course it came when I had nothing else than warriors. Archers were coming in pauirs and triplets, I hadnt have a chance of using stone even, as it was constantly pillaged by archers before their suicide on Paris.
Of course axes also came. Fighting shock warriors against axes is awesome.
When I finally got horses and 2 chariots, I could at least move barbs outside my borders. Now I have even 1 axe! Hah!
I hope Mongolia has similar problems with barbs
350 BC was a bless. Gold popped on capitol hill! I also finally conected dumbos, so my happy cap is even 6!!
----------
Now on 1 AD
7 cities, 5 mainland, 2 on islands

I am not sure if I am patient enough to follow. One of the AIs with Mids and Oracle is sooooo ahead! Even much better than most of other AIs!
