Hey,
@Lexicus and anyone else who saw this in passing.
It does produce the 'if you want to expand you have to take the land from the "barbarians" effect.' I thought I had a pretty good start because the river I founded my capital on ran four tiles down to the sea and I managed to found a second city at the mouth of the river uncontested.
Unfortunately I took a wrong turn on the research path. I started as Napoleon (random) so had farming and the wheel. Paris had immediate access to hilltop pigs and grassland cows so I went with AH first. That worked out well as my immediate build worker had me booming out population and the settler for my port really quick. I also had a barren hilltop that I thought would be metal so I ran mining-BW-IW...and it wasn't. That was the wrong turn. I popped out another settler and built a city three tiles from Paris next to a Carthaginian copper mine hoping to flip it and frantically researched hunting-archery, but about the time my first archer appeared in Paris a neighboring Suleiman, who did have metal, marched in and started carving through my warriors like butter.
So I peaked at three cities controlling a total of thirty tiles, plus two sea tiles. The 'must expand by taking land from barbarians' definitely worked, except as it turned out I
was the barbarians.
