Big Ben - 27 Colosseum – 35 Forbidden City - 26 Oracle - 6 (5+1): Usually the 2nd choice after Pyramid, even more priority than Pyramid in cultural victory. With Pingala combo, it can provide 6 times of GPP(mostly scientists, writers and merchants) of 1 city in very early time, much better than 5 more settlers cost. And if you're lucky enough to get Harvest, you'll save lot of faith on some key GPs which AI will soon get. Pyramids - 30 Temple of Artemis - 22 (25-3): Comparing to Colosseum, it doesn't provide culture, less amenities, low range, and most bonus resources will be harvested in R&F by efficient play. As an ancient wonder, It's hard to build Pyramid/Oracle and still have time/trees to build it - at least in an efficient peaceful game there is no place for it. Among ancient wonders, Colossus was better than it for an extra trader/route, at least few AI build it.
