I'm way behind on my reporting; Aurorarcher has been posting, but here's my side of the story:
At EoT 72, I took another spin on the great person roulette wheel:
It came up merchant. I spent a lot of time pondering what to do with him: a bulb of Horseback Riding would save me ~300 beakers (cost 400, minus discounts). Settling him would give +1 food and +6 gold; a golden age would give ~30 commerce and ~20 hammers, times 9 turns. I finally went with the golden age. I'm way behind, and the extra hammers can be used to build units, infrastructure, and settlers/workers. I'll net fewer beakers than with the bulb, but they will be put into the techs I want most right now. Horseback riding is an important tech and I definitely want it soon, but I think the most important thing is to start being able to summon units.
On turn 74, I gained a trade connection to Aurorarcher. Now I can see his cities and resources:
As expected, he's way ahead of me in development; what really hurts is that he's equal in cities.
I offered him open borders, since it looks like we're pretty far apart and could be friendly. Then, at end of turn, Emmett Kelley's borders popped and I gained contact with xist:
I would much rather open borders with the guy who's last in score than the guy who's first, but it's too late to withdraw the offer.
Turn 75 opened with a flurry of diplo windows:
Accepted, just what I was hoping for. I'm not a big fan of map trades, but I'd like to build trust with the vampire guy and have him look elsewhere for his conquests. Probably not much benefit for me, since Auro's cities will fill my trade route slots. Except:
No quibbles here; Auro already has an overseas route if that settlement to my northeast is indeed an island, so open borders favor me by a little bit. Cotton will give a small boost to his tailors, and I'm not likely to build Deruptus for a while; Ronald McDonald will be building at least two more settlers. Refused.
And a straight-up open borders. Sorry, Auro, my routes are full now. This may result in a bit of a diplo hit from me offering and then refusing open borders, but I'd like to avoid boosting the leader to no benefit for myself. Refused.
I'm not sure xist realized that the trade routes are one-way; I should have offered him my spare sheep as recognition of that. As I always point out, though, this screen overstates the value of foreign trade routes; I am, indeed, getting 2 commerce per city from foreign trade routes, but I'd be gaining 1 commerce from domestic trade routes otherwise. So xist is really giving me +5 commerce, not +10.
Demo and foreign trade screens, spoilered because I already have a ton of pictures:
Finally, a zoomed-out view of xist's exploration. Note
Brian's Bing's borders in the far east; I even have a trade route to him, but no contact. Note also that it took me five tries to get flying camera to line up right; my mouse skills are abominable.
