Concerning the build time, I think we can also work one plain tile to get the 7th
and I cut down a couple of turns for whipping the rest. That's why I said 'about'. I just didn't know exactly how much this whipping 1 pop is atm. Have to look. Is it 44
for 1 pop? Would that be 88 for stone available? Can somebody correct me? If that would be true I think than it is exactly 31 turns.
Working unimproved plains is very unattractive. (I guess we could put a cottage there; that's only slightly better.) And working forest, forest, gold mine, plains at size 4 is not even enough food to feed our city.
Pop rushing is heavily penalized when you're rushing a world wonder. The only effective way to do it is to rush something else and put the overflow into the wonder. See below for one way to do that.
Building city #3 2W of clams, rather than 1SW, is really much better in the medium term, not just the long term. It would get us 4 more land tiles to work, two of which are much-needed hills for production. Unfortunately, it also means it's a really long time before that city is productive. Best we can do is work a coast for 33 turns to grow to size 2, then rush an obelisk, then wait another 15 turns for border expansion.
It's not going to be significantly faster unless we get a religion, or we can switch to Caste System (then we could expand with an artist in just 4 turns).
My current inclination is to go ahead and put the city next to the stone and start working on Pyramids in Fort Smurkz. The value of connecting the stone is what sways it for me; working on the Pyramids will be good whether or not we actually get it.
It's 8 turns to build the settler, and 5 turns to travel, so we could found the city 14 turns from now. Worker needs 2 more turns to finish the mine, and 9 turns for 3 roads, so it can be ready to start the quarry if we have Masonry. Then it's 9 more turns to build the quarry, so we would have stone hooked up 22 turns from now.
In 22 turns, what can we do with Fort Smurkz?
2 turns working rice, forest (food 16/36, warrior 18/22)
1 turn working rice, gold mine (food 18/36, warrior 22/22)
9 turns working rice, gold mine (size 3, food 0/39, workboat 36/45)
2 turns working rice, gold mine, forest (size 3, food 4/39, workboat 46/45)
8 turns working rice, gold mine, forest (food 20/39, granary 82/90)
At this point, we can rush the granary for 1 pop, if we want, and put 90 overflow into the Pyramids. That leaves us at only size 2, but the granary gives us "relatively quick" regrowth to size 4.
Alternatively, we could do the same thing but with obelisk instead of granary, if we would rather have cultural expansion to pop the two huts.
