I remember in civ 5 to see Tlaxcala as one city of the Aztecs, what I thought was outrageous.
Tlaxcala have an unique history as an independent state in the middle of the Triple alliance empire.
I know Tlaxcaltecas should come from Aztlán, that make they also "Aztecs". But, I don't think the Aztecs represent they as well, by opposite of that.
As Evie said, maybe we can have civ 7 without the Aztecs once and have some other meso america nation instead.
The Aztecs are only famous because was the great empire at the time of Spanish conquest, but the greatest empires of meso america was the Toltecs, so they deserve the spot of meso america in Civ 7.
But I don't will mind if instead of Toltecs it come Mixtecs, Zapotecs, Totonacs, Tlaxcaltecs or Teotihuacans.
I just think should be very fun to don't have Aztecs once, meso america is so rich in civilization and there is no need to still doing the same civs over and over again.
I rly hope civ7 be very, very different from previous games.
