OK, I now have a specific request. I would like to add the Congress of Vienna wonder, which will act as a proto-UN (although its resolution list actually is a copy of the Apostolic Palace, except it's not religion-specific and no Diplomatic Victory). I have all the files made up (including the VoteInfo.xml and VoteSourceInfos.xml files). I know this wonder will need modding of CvGame.cpp, which I do not want to try myself.
This is what I would like to have as the major settings:
Member: Any civilization not at war with the owner of the Congress.
Defiance penalty: +5 unhappiness ("The world considers you a villain!", same as UN). I also put in a free SPECIALIST_NOBLE in the <FreeSpecialist> tag of Civ4VoteSourceInfos.
Please let me know which files you need me to provide so that we can add this.
OK, the updated Python files for Via Appia and Golden Spike are ready to go. I would like to ask again about Congress of Vienna. The XML and graphics are done, but I do not know how to get the voting to work. I don't want to upload the wonder to the SVN myself just yet without knowing what will happen once I do.
