What purpose is there to make the nilometer consume the floating gardens? I have only played vox populi a year after I stopped playing No Quitters because it added extra civs and I've always been against that, so I still have a general recollection of what base game Brave New World civs look like, and bonuses to lakes was what the floating gardens was. The food focus of Aztecs always felt natural to me given the valley of Mexico was the main place on the North American continent with the level of population density equivalent to Eurasia prior to settlement. Also, of course you will get overlap between civs, you doubled the unique buildings of each civ, and Civ as a game doesn't have enough mechanics to realistically change how something works that much. The game literally reduces everything ever made creatively to the nebulous thing of culture. As an aside, it feels odd to complain about the early game wonders being so greek focused. It was a literal DLC focused on the seven wonders of the ancient world, of course it will heavily focus hellenic monuments. Your replacement is also something from ~800 years later.
