Does it matter how civilizations or anything else for that matter are listed in the xml? In civilizations, the civilizations are sorted alphabetically organized, if I reorder them into cultural groups, will that make a difference of any kind?
I think it matters for the selection screens when you launch your games. Well maybe not for Civilizations but for Leaders.
Buildings and units appear in your lists of stuff to build in the cities as per their order in the class infos files (after the sorting of units, buildings & wonders).
