Okay, played 25 turns. I poke around and notice something that Sulla might have missed

:
So Joao's pretty close. Capital pressue is going to be right on top of Poverty Point. In fact, once he gets his third border pop, we won't have any forest tiles to work if we don't get a border pop of our own. Stone still has to be the target, and no delays! I continue scouting our land, having three Warriors early helps quite a bit in that department, us Worker first people aren't used to it. Mining comes in and I select Bronze Working (an event would speed this up to the tune of 23 beakers

). Joao is sloppy popping huts near his capital, and it pays off in spades for us:
On the downside, we lose our easternmost Warrior to a Lion but I think Masonry still made that a pretty good turn. Our newly designated easternmost Warrior finds another hut amongst some Gold, and it gives him, well, gold (28). After sweeping out the fog in the middle he heads over to a nice hill that combined with the extra border pop from Hinduism and Joao's proximity allows a fog busted path to the Stone for our Settler, allowing the other Warrior to continue exploring. Wang Kon found us, and this guy eventually found Wang Kon:
He is due east of Joao and north of the choke point, of course. You can see I selected Sailing after Bronze Working. I also started another Warrior after the Settler completed. I noodled on a Dog Solider but we need quantity, not quality right now. I'm banking on Noble barbarians to be a bit later, and we can always use them for garrison. Poverty Point was founded on my final turn:
Ouch on the 1.42 distance from Palace maintenance. I queue up a Totem Pole, no hammers invested. Other things are important, but again once Joao gets his third border pop we lose all useful tiles. It also completes the seal

. Now, my passionate defense for Gems as the next city site:
Those forests are the Pyramids, with enough food left over to run a plains forest and a 2 GPP/6 beaker scientist specialist (net 5 GPP for this city). The other reason would be a dearth of good spots. Here is our land with river highlighting:
It is kind of hard to tell with all the fancy colors, but here is what each city brings to the table:
#2 - 1 plains forest, a scientist, 8 chops, Gems
#3 - 3 grassland forest, a scientist, 5 chops
#4 - 2 grassland forest, a grassland horse, a scientist, 8 chops, Wine
#5 - 3 grassland forest, plains forest, plains forest incense, 5 chops, Deer
Marble is definitely coastal, we'll want to found it for the GL eventually. I zoomed in and around the Copper tile. I
think she might be coastal, only time will tell. I believe the Gems, Wine (both wines), Deer and any other resource should be traded for cash as soon as we have Currency, so they should be considered 10ish gold each. True it won't be for a little while, but who else thinks Currency is the next tech to go for after Mathematics?
Good luck to the next guy
