If we are going off of the revolutionary period only, I'd even consider Haiti a winner in that regard.Because that's a standard that grossly favor overrepresentation of European colonial powers (and their offshots) at the expanse of the rest of the world, and erase much of the diversity of human civilization.
More than that, this is the (nonsensical) idea that being a civilization is a "reward" ford historical success. It should not be (and never was, considering the Zulu for all they won a few battle ended up by most every relevant metric worse off than Haiti), because at its heart civilization is a What If game, and taking the losers of history and making them win is part and parcel of what makes the game. Which you can't do if you only include the historical winners in the game.
I wouldn't even necessarily call myself a Byzantine fanboy either. Before the NFP I considered the idea of Justinian/Theodora as a potential Roman alternative leader, only because I didn't reasonably see 9 more civs getting in the game in a hypothetical 3rd expansion. I do agree though that by the time Basil II became emperor the Byzantines are way more different and wouldn't fit under a Roman civ.I think the big issue is, you didn't even ask why me, or @Alexander's Hetaroi, supported Byzantine inclusion, but assumed it must be the same as, "the fanboys." But, that being said, I accept your apology.
I'm a Dromon fanboy though, so anyway to get them in the game is a plus. I would want it to be a LUU if Justinian/Theodora happened to just be a Roman alt leader.
Haitian Creole is still a French-derived language. And while Voodoo isn't necessarily unique to Haiti either, I'd still give some voodoo elements into their design considering Voodoo was a component of the revolution.Other thing very cool about Haiti is it own religion, the Voodoo (who in Haitian Creyole it's Vodóu)
Who can be used to design a cool unique unit as a voodoo priest or their own heroe can be a Voodoo Lwá, as Baron Samedi.
Also, the Haitian have their own language, the Creyole. I know the Haitian revolutionary speak more often French then Creyole, but, for a game purpose, should be nice if they speak Creyole.
And nowadays have Haitian Creyole even in Duolingo, I also made some lections.
