Two reasons why farms/specialists are better: quicker reward & you can work the mines instead of the using specialists when needed (for buildings). Two reasons why it's a bad idea: you may not get the type of specialist that you want and you may not have that much use for the specialist.
I would like to elaborate more on this issue but I fear to breach the spoiler rules

. Perhaps we can pick this up in the next spoiler, since I agree that much can be learned it?
Ok, see you in the next spoiler. I only want to say now that with cottages you can work the mines all the time. And then, you still have spare food for a few specialists.
Copper was too far away, so he went to settle in the southern flood plains.
I think that in large maps the maintenance costs associated to distance are modified accordingly, so it was not so far away.
Settler protected by a worker went west to found barcelona on the coast.
Yes, playing safe is very important.
Now my spoiler:
jesusin, contender. Goal: fastest conquest (or diplo)
I want to conquest the world in other to learn how large a large map is. So no culture this month, although large and Epic invites to culture and fast game in real time.
As announced in the pregame thread, I moved my settler N and NW. It ended up settling on the fourth turn in the mouth of the river, with pigs and fish (and iron later on). I am happy with the extra food. The first session was plaged with little mistakes, like not micromanaging when producing a settler or lousy production selections. Had this game been Quick speed, I would have lost all hopes of an award, but being Epic, little mistakes are not important.
I produced a workboat first, then worker, then 2 warriors (1 had died), then the settler for the 2gold+gems+rice+pigs site. The warriors had to fight the bear to clear the path for the settler.
I researched AH (hunting first) and Pottery (wheel first) as priorities. Then mining, BW, Wri, IW, and Alphabet to extort Peter.
Exploration was a disaster, I had seen the whole map but a little peace of territory just N of my capital in 2380BC, 55 turns into the game... and that's were Peter was.
Peter was a fool that had settled his capital just 1 tile W of the greeeeat spot he could have chosen. Worker stolen in 2080BC, the only archer in the capital didn't attack, peace in 10 turns, 2nd worker stolen 10 turns later, peace again. In peacetime, what did he do? By 280BC he had only 3 cities, no resources connected and the Pyramids in Moscu. So I dowed, took Moscu (oh, how much I would have liked to raze it) and the ridiculous stone-copper city without food and extorted Agriculture and Sailing for peace (he valued them a lot, as monopoly techs, so I didn't get Maths for free). In 20AD I worker stole again and relieved Peter of his duties as a leader.
After capital and the obvious second city site, my third city went to the copper, with rice, 4FP and elephants. The fourth one went SW of the marble, among FPs. The last one, after taking 3 cities from Peter, was built near the horses.
Wonders: stolen Pyramids, GLIB in 10BC.
GPs: 1 scientist for an Academy in Madrid.
Economy: emphasis on cottages.
The brave barbarian: while I was finishing Peter I had a single warrior in Madrid. Barbs had found a city in the original starting place (is this an ironic message to those who founded in place?) and sent an archer north. So GLIB construction had to stop while I whipped a Sword. The promoted Sword only scratched the archer in open, so the warrior could not even try to finish him. The experience the barb had won in the fight made him wiser so, instead of pillaging a 50-turns-worked-cottage, he climbed to the pigs hill. Should I attack him with my new Sword, considering that I only had a 93% probability of winning? I new I shouldn't. The second Sword died too. Oh, my, what will happen to Madrid inhabitants if they lose the access to 'jamón de pata negra'? So, in a desperate move, I decided to attack with my warrior in order to protect the pigs. The odds were in my favor, but only 98'3%, so I was really scared. I won. Lesson learnt, when your capital is in danger, don't call some youngsters with their brand new weapons, let a 4000 years old man with a stick do the job!
After Masonry,Poly, Lite, MC and Maths, an important decision took place. Construction was not an option, since Peter would be dead before I could have researched it. Currency-CoL-CS would have given me religion, money and bureaucracy. But in the same time I could research Machinery, Compass and Caravels, allowing me to trade with the other continent(s). That's what I chose.
I will now take barb cities (one is missplaced and will be razed) with my remaining units, while teching full speed towards ships.
I feel I have been short of workers the whole game. And that I have had too many cities (good in the long run, but bad for research in the short term).
