Pre-flight: Mostly, everything looks pretty good. We do have a few relatively productive cities building courthouses; change a couple to aqueducts (we can use the unit support) and a couple to markets. We will want courthouses eventually, but there are more useful things to build now.
Given that we've got the northern island halfway settled, I think I'll keep building settlers until we have the whole thing. I'd hate for, say, France to found a city there and start flipping our cities. It's not great land, but we need all that we can grab peacefully.
In
410, Education comes in. Astronomy ordered up, due in 6.
Unis are an interesting question. We need them, but we need military, too. So I'm going to let the MI's finish. Hopefully Seoul can take over the military duties soon (though we could use a cathedral there, too...).
In
440, we finish the Sistine Chapel.
Now if we only had any cathedrals, we'd be set. Seoul orders up...a library.
Apparently some deals just expired, because we lost our sources of dyes, ivory, and silks. We really do need those luxuries. And Gunpowder has been spreading, so hopefully the price has gotten reasonable. So it looks like it's time for a round of trading.
No point in hoarding Theology now, so I sell it to Sumeria for dyes and some pocket change. As much as I hate to trade techs for luxuries, the AI civs don't have much else to give us, so I trade Joan Education for ivory and silks. Hopefully we can build some cathedrals in the next 20 turns and not be so dependent on foreign luxuries.
The AI civs must be researching Education, because I can't get anybody to trade me Gunpowder for it straight up. The best I can get is Edu + 75 gold to William for Gunpowder. And, naturally, we have no saltpeter on our continent. Or Iron island. Or the northern island. Where are all the resources this game?
In
450, Egypt builds Sun Tzu's. France cascade-builds Leo's.
In
470, Astronomy comes in. Research set to Banking. Our prebuild in Pusan changed to Cop's, due in 14.
In
480, the Netherlands develop Chemistry. We might want to trade for that in a few turns so we can research Physics and head for Newton's.
In
490, Sumeria builds Knights Templar. Maybe we should think about beefing up our defenses...
I kept Wonsan as a 2-turn worker factory, and recommend continuing this. We need workers, especially on the two islands. I didn't really understand why we were keeping so many forests around (most of our cities, especially the half-tundra ones, need food, not shields), so I cut some of them down and worked on getting irrigation out to the cities that needed it. That's mostly complete, so we can probably start shipping workers to the islands.
I also strongly recommend some happy buildings, since the price for all the luxes we're importing is just going to go up. Seoul can probably use a cathedral when its university finishes, Pusan perhaps when it finishes Cop's (or maybe go for Newton's first?), and the other cities when they grow a little more. Do we want to think about going for Bach's Cathedral if Music Theory turns up soon?
Be careful about trading Astronomy - the Great Library hasn't been built yet, so we could lose Cop's to a cascade.
