You know, The Capo's requested Al-Kahina.
I know but Al-Kahina is much later, an entirely different ethnic group actually. She's already seventh century and Jewish. It's more modern berber after all the middle-eastern influx.
I'm requesting ancient Libyan, who are berber but perhaps best described as the ethnic group that modern berber came out of, pre-judaism, pre-islam, conquerors of ancient Egpyt. They were basically the indigenous people of the Sahara (even before the Sahara was a desert). Plus the ancient Greeks separated the ancient Libyans / Berbers into two ethnic / cultural groups; those west of a specific lake who were more migratory (Al-Kahina is best described as descendants of them in a more Maghreb thinking) and those east of the lake that were more sedentary and major agricultural powers of pre-desert Sahara (my request).
Al-Kahina is more a Maghreb leaderhead (though still an excellent suggestion, and if someone was making a general berber civ - like the current Native American or Polynesian - using her and my request would make great leaderheads) but an entirely different representation than what I am suggesting.
Basically, It's like someone requesting a leader for ancient Aksum and then suggesting a more modern Ethiopia, Rome and suggesting an Italian, or an Zorastian Persian and suggesting someone from more Islamic Persia/Iran.
Al-Kahina was perhaps undoubtedly more important for Berber modern 'national' identity, but in terms of world history the ancient Libyan 'Berber' were more important due to their conquest of Egypt and being major allies with the Sea Peoples.
And besides, Berbers have, in all honesty, basically no representation in Civ. Two leaderhead is hardly requesting too much for something that has zero representation.
