Pre-req's for Wonders

[Xmudder]

Anyone want to bet that you need 5 temples to build the Oracle?
5 Libraries to build the Great Library
5 City Walls to build the Great Wall
Colossus would require Bronze to build
5 Harbors to build the Great Lighthouse
Pyramids ???
Hanging Gardens ???
5 barracks for Art of War
War College needs a great leader to enable.
Sistene Chapel ???
5 Cathedrals to build the Great Cathedral
5 Universities Great Observatory
5 Marketplaces for Adam's Smith Trading Post
5 Ports to build Magellen's Expedition
5 Banks to build Wall Street
5 SAM batteries to build SDI
Manhattan Project would need Uranium.
Apollo Program ???
Longevity ???
There can be only 1 UN

36 choices... 12 unique, 24 small ones that every civ can have. I think anything with "great" in its name is a small wonder.

I don't think Great wonders need any prerequisite number of buildings, only a prerequisite tech, but small wonders (wall street, SDI) do need prerequisite buildings. Also, I think the Great Library and Lighthouse are great wonders; they show up as being owned by 1 civ on the wonders screen in the screenshots.

I don't have an opinion as to the likelyhood or quality of this idea, but woudln't it make sense for the UN to require 5 courthouses(if you want to go along with the same style of the others) and/or embassies in every nation?
