Yeah, although Civ6 has a strong focus on personality leaders, which most certainly justified the inclusion of Simon Bolivar. Also, Gran Colombia was the most popular request among Hispanic nations, although less than Vietnam, Navajo and Italy, as we can see in the poll.
Given that Firaxis is including common fan requests, I wonder what happens unce they haven't added an Italian representation yet
. If they think that a civilization called "Italy" would be overlapping with Rome, they could at least add Florence, Venice (unlikely now) or Genoa.
I think it would be very bizarre not to have a Hispanic nation in the game while we have three former British colonies. My personal choice would be Argentina, but I'm perfectly fine with Gran Colombia.
