Yea, I am definately no where close to anysort of conclusion on this. This is the first time I have ever touched coding, so its a bit confusing, and I am sure I will have more questions after this one.

The first question I have is about the CIV4CivilizationInfos.xml

I was using This Tutorial to help me make the civ, but since it is for Vanilla Civ, I realized that I might need to use some different files.

Which files should I use to add a civ to FFH2?

This is what I have so far...Not much.

The files in your download appear to be vanliia civ files, not FfH files. I would recommend using the FfH files to start with. If you have excel I would also suggest using the editor to add another civ. Not that it can do everything, it doesnt do art defines, but it should help.

Okies, I was working on it last night and I think I got all of the necessary Text for AI use, and got the the Civilization added. In the Excel file I edited the following

-Civilizations
-Diplomacy
-Leaders
-Text

I am not sure that I did this correctly though, I would greatly appreciate some sort of peer edit.

This is the Excel file. (http://forums.civfanatics.com/uploads/63875/FfH_Editor_my_project.rar)
