Thanks!
Nope, Stonehenge... it's for the money. Once the capital reaches size 4, I think we can start on Settler, Worker again.
Besides, I thought that since the city was labeled as a GP farm it is improper to have a wonder at all IN THAT CITY, unless it's National Epic (pollutes the GP points, but only presents a small risk compared to the benefit of improved points) or a wonder that enables adding specialists of a desired profession (like Angkor Wat or Great Library). Pyramids and Parthenon are great, but could be left to other cities.
Actually I did play 30 turns already, I guess I should really pass the game on.
Who's next!? I agree with Mr. Xyqtt and recommend settling on the new site marked X. Also let's head for Writing and build (whip) that Library so we can have our Academy ASAP.
I think we should also REX to 4 cities, build military in 3 of those cities and rush Roosevelt. Capital can keep making our scientists (and maybe artist/merchant in the future with caste system), and we can also settle great scientists there (if the free tech isn't that great).
