Oracle/MC in Gold City T105 1375BC (1400BC game log)
That's a date that I think a lot of us could agree would make for a reasonably safe Oracle date (there is no "risk-free" option here, but this approach definitely reduces the risk).
Research: hunting-writing-myst-masonry-medit-priest (poly instead of medit 1t later)
Okay, I understand that you're still going for the 2-Great-Scientist without-Pacifism approach, but do you think that your Gold-City-Oracle scenario could still work well for a Lightbulbed Philosophy scenario? If not, why not?
Cities: Gold-Fur-Marble (on the marble)
Do you see an issue with the fact that Marble City's borders would need to expand before we could net a Clam there?
Which City do you plan to use for generating your second Great Scientist? Or would you need 3 Great People now that you're Oracling Metal Casting instead of Machinery, and if so, which Cities? Maybe the capital would generate Great People #1 and #3?
Solid REX with only one wkr
Definitely cool.
Gold City borders expand in 2t with 3rd wb already waiting
The borders would expand with a Library just the same, albeit probably slower.
Does the early second Cultural border expansion help us in fog-busting for Barb Galleys? Also, are Barb Galleys attracted by Cultural borders or just by the Seafood Resources... i.e. does expanding our borders help keep away Barb Galleys that might otherwise "find" our Seafood but possibly at the same time attract Barb Galleys that seek out our Cultural borders? Or do the Barb Galleys generally ignoredthe Cultural borders?
Marble City will have two seafood tiles (or three

)
If there is a third Seafood Resource, then either of the two Marble City locations will get it, so let's not count it.
The question becomes: does the delay in expanding Marble City's borders help us more than it hurts us?
Also, would you Chop the Marble City's Forest (the one that you didn't settle on) into a Monument or into a Granary?
Our worker is now available to pasture the pigs or quarry the stone
Maybe it should first Chop that Forest by the Marble City that I just mentioned?
Gold City doesn't have its granary yet
No worries, one can be whipped in a Food-heavy location soon enough. How did you build the Oracle anyway? Did you mostly use whip overflow to build it? Forest Chop into it? Base Hammer production?
Personally, I would go with the variant that delays pop6 in Paris but gets the lighthouse done beforehand.
That idea is in-line with how I played the test run that we followed for my turnset, so I support it.
Paris is at 9

so it can work 2 sci and 3pop settlers
Problem 1: Early Writing gives us a lot of mileage (exploration, TRs, research, GS gpps), but the happiness cap in Paris causes a conflict between REX and hiring 2 sci.
Just to play devil's advocate, would it possibly make sense to build the Oracle in Paris and thus not have to worry about getting sufficient Happiness to be able to hire 2 Scientists while simultaneously spamming Settlers?
Up until we get Bureaucracy, which is a long way off, it could be argued that the Gold roughly equals the Palace in terms of Commerce, so building a Library in Gold City versus building one in the capital won't necessarily make a difference in our tech rate.
Problem 2: We want to REX but we're late starting on the Oracle. Building it in Paris pollutes our gene pool. Building it in Marble City is hard to do before ~1300BC, costs a ton of worker turns, and slows down our REX by forcing us to settle one of our weaker city next (UNLESS it has another seafood in that fogged tile!!!

).
Have we considered, instead of settling Fur City, settling Stone City and building the Oracle in Stone City?
We all know that Stone City could use a border pop if we place it in the location that shares the capital's GH Mine.
Would it be feasible to build the Oracle in Stone City by settling Marble City on the Marble, or did you need to do something tricky like use a lot of whip overflow us to get the Oracle completed on time?
Doing so would give us 3 Great Person Farms: the capital, Gold City, and Marble City, although, as you suggested, the capital might have to wait a little bit to start on Scientists since it needs more Happiness... but it would still be POSSIBLE to try and generate a Great Scientist in both Gold City and the capital this way. I just don't know how crazy-long it would take to Hammer-out the Oracle in Stone City.
If the Stone City idea is unworkable, then I still am not convinced that building the Oracle in Gold City is necessarily better than building it in the capital. Gold City is slightly more suitable for hiring Specialists, since it only has 4 good squares to work compared to the capital's 5 good squares. Still, that difference is, arguably, negligible, so if the reverse is not possible, then it's still a decent plan to build the Oracle in Gold City.
