Please note that the real game is not paused. I took screenshots from the latest turn's Demographics and Top 5 Cities screens from both the real game and the test game.
In the real game, the AIs are generally ahead in GNP, Hammers, and Food, with one exception being that in the test game, 1 AI has a higher amount of Hammers.
I would thus tend to think that once we learn Alphabet, whatever tech level the AIs are at in the test game should be fairly representative of the real game, and at least the test game is unlikely to have the AIs being further ahead than in the real game.
As I mentioned earlier, meeting AIs can cause them to duplicate research on techs that we have learned (or started with, such as The Wheel), so that's another reason to delay contact with them.
One settling location that we haven't considered was over by the Sheep that have been revealed. Theoretically, we could settle on top of the western Sheep, getting another Sheep plus 2 Fish in our big fat cross. I'm not particularly sold on the idea, though, as there isn't a good square for a Worker to improve initially and we won't have Bronze Working in time to Whip a Work Boat at City Size 2, which would be one of the benefits of settling on top of a 3-Food square (being able to grow a bit faster).
Germany may settle a City up there for us anyway, so it probably does make sense to settle closer to home for reducing Maintenance Costs. If Germany doesn't settle there, it might make for a good City 4 location.
I do think that it is a very interesting idea to settle to the south-east for the 2nd Fur. What did we do while building a Work Boat? Were we working the Fur square? If so, that's what, 2 Hammers per turn (including the City Centre's square) for 11 turns (when we hit Size 2), then 4 Hammers per turn at Size 2 (while also working a GH For square) for 2 turns, giving us 22 + 8 = 30 Hammers for our Work Boat? We'd then be working both a Fur and a Fish, which are two Commerce-giving squares. How did the Worker actions work out? By the looks of it, we'd only need 1 piece of Road to connect up our Trade Routes. We also wouldn't need to use our Missionary in City 2. We'd miss out on the Sheep down there, but the Sheep could be later partnered with the Gems square in a different City.
So, perhaps that approach is worth running with...
Build Settler 2 at Size 3 after completing Warrior 2
Settle 1 E of the south-east Fur while building a Work Boat
After completing Settler 2, grow Paris to Size 4, then build Settler 3
Try to get both Fur Resources improved ASAP, and also make it a priority to build a Road between the south-east City and Paris' River (it looks like just 1 square of Road would be required, but if there's a way to build a Road to speed up the progress of Settler 2 by 1 turn, then doing so is also an option)
Skip Mining and go straight for Alphabet after Fishing
If we can find an approach that excels over other approaches, then we don't necessarily need to do a ton of testing. For example, settling City 2 by the second Fur sounds like our best Commerce-oriented approach. When City 2 hits Size 3, we could work a 1-Food, 2-Commerce Coast square to further push our way forward to Alphabet.
Another opening could be to focus on production, but it sounds like pigswill wasn't able to make Mining-only work for getting us a Library in City 2, meaning that a production-oriented approach would probably require us teching Mining + Bronze Working + Pottery. It's arguable that with that many techs ahead of us, settling City 2 by the Fur could still be a good play, getting us 2 Fur Resources' worth of Commerce to power our way through the techs that we want to research.
The only real downside is the slower growth of City 2 to Size 2, but we'd be emphasizing Commerce to get us through "the hump" of techs to Alphabet, so that slower growth might be worth it, especially since Cities settled to the west or the north-east don't offer a second Commerce square after working on a Fish square.
