[Cross post with Rolo]
I'm betting the thing with the red cross on top is the Red Cross, which would make 6 nat'l wonders with Scotland Yard. Dikes are Dutch, Trading Posts are Viking, ikhanda, dun, totem pole?? -- how can they mix different civs' UBs? [For that matter, how can you have more than 2 nat'l wonders without OCC?] And what happens when we conquer Atlantis? The UBs revert to our equivalents, any nat'l wonders we already have are lost from Atlantis, but if there are more than 2 remaining nat'l wonders there, which would be lost? Random, or by date of construction?
What really confuses me is that I don't know of any building that gives an extra (beyond lighthouse) food to sea tiles.
While it's nice to see what the barbs have, we'll have plenty of time to sort that out before we can even think about attacking Atlantis. In the near term (5 turns or so), there's no reason we can't just forge ahead, right? We want to explore with our airship, research deeper into the tech tree for trade bait (until/unless it's clear that we won't find anyone to trade with), hook up the copper, and settle a city.
As a starting point for discussion, I'd say that over the next 3 turns we should have the workers road to and mine the copper, build 1 archer and send him toward the forest tile W of the mountain and fortify (assuming no barb comes near), start a settler, research IW (since knowing where there's iron may be quite important in choosing a city site) and then Paper (?), and send our airship to recon from 8E, 6S5W, and 8W.
