I was miss-remembering some map details slightly. I have looked at my 0AD game again, and have many more details.
Firstly, even more important than the second city is the position of the first city (capital). In my view, settling on the gold hill was a significant inaccuracy, at least if you plan to play a Oxford/tech-ing game. As already stated, it idles the worker for 5 turns, but more importantly, compare to settling S-SW to have wheat in the BFC. Without the wheat, it is very slow growth to get to 3 gold mines, and requires farming 2 flood plains early. With the Wheat, at size 5, one can work a cottage or oasis instead; have one less farm (saving 8 worker turns). Also, the early wheat health further increases the growth speed.
Here is a list of my cities, in founding order, with location, reasoning, and there contribution to science (@100 bpt) at 1AD.
1. Capital. N-NW of wheat. 131 bpt (includes Acad and Beuro)
2. 1N of Deer to pick up all the Gems. Happy bonus and early research monster. 40 bpt
3. 1W of Iron (did not know that at time of finding). Connected by river. Shares one capital gold while it grows. Another good research city. 29 bpt
4. 4N of dear. N the river to act as a river connector for city 2 to the rest of the empire. Also helps develop the capital cottage. 27 bpt
5. 1S of banana. Access to coast, and fish, Banana, Cow (and a rice once the jungle is cleared, which has not yet happened at 1AD.) Can share a Gem when needed. Main role is GP farm. 21 bpt
6. 2S of south most Silver. Also on the river, and with 2 gold + silver, another good research city. 30 bpt
7. 1S of stone for Fish + Clam (and a gems). Intended as Moari city. 19 bpt
8. 1S of horse for 2 silvers. Still on river. 16 bpt.
9. Captured from Zara: AW of spice, with 2 cows, silver, fish. Currently in revolt.
10. Captured from Zara: 1N of sheep. Can share silver, and use crab. 16 bpt
11. On incense, 1N of clam. 6 bpt
Tech path:
Agriculture (3760), Wheel (3520), Pottery (3280), Writing (2840), BW (2600), Math (2160), Currency (1680), CoL (1360), Fishing (1320), Alpha (1160; from trade), Sailing + Masonry + Sailing (1120; from trade), CS (775 – revolt Beuro + Caste), Construction (650; to deal with Zara), Paper (500) , Mysticism (450), Calendar (450; from trade), Meditation (425), Priesthood (325), MC (250), Education (175; with a bulb), Feudalism (150; trade)
Oracle was built in foreign land in 1320 BTW, and GLH in 1240, MIds in 1160.
My first GS came in 525, and became an academy.
In terms on infrastructure, I have:
Units: 10 Workers, 15 military (warriors, chariots, catapults, swords, etc.) and one WB.
Buildings: 8 granaries, 5 libs, 4 courthouse, 2 forge, 1 university
To be clear, Oxford was not started yet. Another 4 Unis were still under construction. The planed date given above simply added the Uni production time to the Oxford build time.
Improvements: 22 mines, 3 farms, 3 pasture, 2 nets, 2 camps, 2 cottage, 1 village, 1 workshop, 1 quarry and 1 plantation.
My FOREIGN trade routes were bringing in 54 gpt, and I was selling 2xgold for another 9 gpt
