With native-speaking leaders, I will be even more biased to permanently include or exclude some civs from my games (I usually play the Greeks):
All-in: Japanese, Inca, French, Ottomans, Romans, Arabs
All-out: Songhai, English, Americans, Indians
For Mongols, Aztecs, Chinese, Vikings, Russians I will wait to see the voice acting. I wonder if Egyptians will use Arabic voice acting (with an Egyptian dialect), but I seldom play against them.
