Like advances and most of the units, the new wonders have already been introduced by Wes Whitaker’s Med-Mod. I am still thinking about ’de-localizing’ all wonders some day, because I find it a bit annoying to build the "Temple Of Karnak" outside Egypt or the "London Exchange" in any city that’s not London. But I ran out of ideas regarding this issue — and therefore put it on hold. However these are the wonders that have been added / renamed in relation to the original game:
Wonders of the Ancient Age.
Wonders of the Industrial Age.
Wonders of the Late Modern Age.
