Maori, maybe in Civ 6, since we have Polynesia. They have merits. But New Zealand? No way. Our military consists of three helicopters, two boats and a couple of guys with Nerf guns.
Are you sure? I thought they decommissioned the Nerf brigades last year.
I am really looking forward to seeing what the other four new Civilizations are in this expansion; particularly what their "Uniques" are. Though I do think a few of the suggestions in this thread are a bit far fetched, Brazil and Indonesia for example; despite they might be a fun civ to play, only seem in there for their geographical importance rather than any historical legacy (but then again some of the current choices fall into that category; Songhai, Polynesia, I look at you)
But I'll place money that the Zulu are in there. The Zulu (no matter how important they were in real life) have been a center for Civ since the Original.
I stand by my dislike of Justinian for a couple of reasons:
One, he bankrupted the Eastern Roman Empire
Second, the Empire when he ruled it still seemed a bit western facing. He is referred to as the last Roman Emperor and he spoke Latin. He focused on trying to recapture Rome.
The later Empire that spoke Greek and was a hybrid of east and west seems a bit better. I like Alexius Comnenus, but I've also heard good arguments for Basil II. In other words, someone who spoke Greek.
It's also possible it would be Justinian's wife, Theodra, but that would compound my objections.
How about someone from the Palaiologos lineage? They managed to recapture Constantinople from the Latins. Maybe Michael VIII? Or even better, Constantine XI (heh)?
I'd place my chips on Basil I however for Byzantine Emperor, anyway. he seems like the only decent one of them.
