I don't know in which forum this thread originated, but, anyway...
This game is back-compatible (or however you say it English)!
This means that if you have C3C you can play all three types of maps. In the editor you can use the File\Import function to import a bic or bix, and remake it to a biq.
DesertWolfs definitions were correct, but his conclusion was wrong.
As to Flamegrapes request, that's not possible, as C3C includes features not in civ3.
Good luck.
