OK, I think that my computer is back in operational order (after much wrangling and frustration, it seems that a simple system restore was all that was necessary . . .). I'm going to make sure that I can open Civ and the save before I confirm, because my laptop crashes just as I was opening Civ (probably a coincidence, but who knows).
I'm for settling the Plains Hill, if possible. We can always drop a settler there first to see if we're allowed to. Would it be legal to set up that situation in World Builder to see if the game mechanics allow another city to be settled in such a situation?
Edit: I've successfully opened the save, so I think I'm good to go when we're ready.
What I understand so far: Grow Moscow to happy limit, building Library for beakers, maybe military buildings after that? Then Settlers, a few workers (not that I'd get that far).
St. Pete: Military builds, barracks, etc. Should I throw in a Monastery so that we can spread the religion around a bit? If nothing else, it would let us build temples and Monasteries (beakers) and eventually a Cathedral for extra culture (put one in St. Pete to push back Indian culture?).
Settle Moai (still to be decided) and gold site.
