Correct me if I am wrong, but didn't the Israelis decend from the Hittites/Same with the Palestinians? We need to differentiate between civilizations and nationalities. Granted, this mistake has already been made (France, America, Spain...) I'd like to see Assyria, however, didn't Persia decend from the Assyrians?
The French and Spanish are decendents of the Gauls...who are an offshoot of Germanic tribes...
I think Ethiopia or Polynesia or the Sioux are the only good choices left.
Also, one needs to distinguish the Ottomans from the Byzantians. The Byzantians are Roman-Greek-Phoenician. The Ottomans are united horse tribes of Arabic decent. The Byzantians were commercial, religious, while the Ottomans were more Militeristic, Commercial. Anyway....
Here are the civs that really need to be added, as they're absence is a large void in the historical representation.
Ethiopians, Phonecians (invented numbers, the alphabet, commercial standards...), Sioux (More advanced than the Iriquois), remove the English and America, and Spain, and the Scandinavians, introduce the Franks, the Iberians, and the Guals, keep the Celts, keep the Native American civs, add the Sioux. Keep the old Arabian and Asian civs, introduce the Phonecians, keep the Greeks and the Romans, introduce the slovakians, change the Germans to the Germanic Tribes. Introduce the Ethiopians, keep the Egyptians, introduce the Hittites and the Philistines, keep the Zulu. Remove the Persians, introduce the Assyrians, keep the Babylonians, and the Sumerians.
That's all that should be in this game

I may be missing a few of the ancient South East Asian civs and some of the early civs in the Middle East.
In my mind, it's the anciant civs, not the modern nations they gave birth to, which should be the focus of this game.
