That's a good question about the Great Wall, Kylearan. I'm going to assume that someone out there built the wonder from completion in a mere 10 turns. If they were Industrious, or had stone, it's certainly not out of the question. The Great Wall is dirt cheap as wonders go.
Let's see... We've gotten a little whip-happy of late, which is fine, but now we have to back off for a little bit at Madrid (which is suffering the last couple turns of double-whip unhappiness). The current builds seem fine to me, except I still don't get the monument construction at kwaDuzka.
We can hopefully rely on religious spread for free culture there. Why not build the granary first? Unless playing a Charismatic civ, I try to avoid building monuments unless absolutely necessary. That's 45 shields that could have been a unit or halfway to a granary (or a FULL granary in this case, because we're Expansive!) I wouldn't go changing now, with 14 shields already invested, it's just something I probably wouldn't have done.
Topic for discussion: do we want to pursue the Oracle or not? If so, we must immediately swap Madrid over to the wonder when Priesthood finishes. We can reach size 6 and 15 shields/turn there (working the two clams, plus two plains hills and two grassland hills) for pretty speedy construction. Of course, this is Emperor, so we might already be too late. One way or another, we need to decide how to proceed as a team before moving forward. If we pass on the Oracle, I think an axe or two out of Madrid would be the next logical step.
We should also think about whether or not to swap to Christianity soon. That would boost relations with Toku, plus open up another happy face in Madrid. The downside would be no border expansion if Islam spreads to kwaDuza instead.
That's all I can think of for now. Good luck to sunrise tonight.
