It was a rough start in this one. The barbs were much more numerous than I remembered. I put a 2nd city just west of London and a 3rd one to the south, and then I found myself looking for usable land. I had looked far to the west where the lake with whale was, but a barb city popped up before my Settler could get there. Then the city I founded with that Settler got destroyed by a barb Axe.
I did complete the CS Sling (part of the reason I was slower in expansion). I worked my way to Machinery and started cranking out Maces... and now I'm not sure how far this goes by 1 AD, so I will continue in the final spoiler.
