There are some unaccurate usages of the word ‘acropolis’ in the game.
An acropolis is a citadel or high fortified area of an ancient Greek city (https://www.dictionary.com/browse/acropolis). When it is not Greek, we should call it citadel (https://www.dictionary.com/browse/citadel). When we do not mean the fortress, but the high ground area, plateau is the right word for it (https://www.dictionary.com/browse/plateau).
I also considered renaming affected files accordingly, but the patch was huge and I could not upload it to Phabricator.
