I only play with 2 files, all other files are out of my scope 

I play with all the files
how about adding a %age boost to culture? (as specified by Dacubz)
Also you said you were concerned about when another player takes a wonder city the culture bonuses (or if the plot changes hands) when I have a fix for the city changes hands: When the city is lost the civ loses the cultural bonus in that city (-4000 culture) and then the new owner will gain 4000 culture when they obtain their full BFC (ie they reach 10 Culture)
For the plot change, I could put a check for it every turn but it might cause some lag...
@voykhah, can you extract 3ds from max? of sp i can help convert it to nifskope
