All late colonies in history like USA, India etc are full countries and sometimes even put the homecountry in their shadows. In game you got free cities and player(Human,AI)nations-

Will colonies broken off being fully fledged oponents?

Wouldn't make sense, as the colonies have fewer Eras to gain fame. An empire can be vassalized, then break free, though.

I guess you right

seria interesante que las regiones o colonias reclamen independencia según algunos factores

Humankind is way too gamey to incorporate things like this. Best resemblance of these events you're gonna get is if a city breaks off in riots due to internal unrest.

There is no reason why if this is not in the base game, that it would be added as a DLC at one point. One thing Civ fails to deliver is the rise and fall of nations.

It may not be a full AI fraction, but if a territory's stability is low enough, the territory and the city will rebel and turn into an Independent People faction. That's the closest thing we have in Lucy to "colony independence".

In a related note, I would like to see "colonies" found on the foreign continent a bit more different from cities on the old continent.

Currently, there is only "Colonization" civic that covers this topic, and it will only give newly founded cities a status effect - Vassalized City (+industry bonus) or Naturalized City (+stability bonus), which will only last 10 turns. After the status effect ended, your oversea territory will behave the exact same as your home/metropolitan territory, which is not really how things work IRL.

I doubt the game codes can handle something as dramatic as "colonies gain independence and become full culture", but I hope a comparatively smaller difference between home cities and oversea cities - therefore fulfill the currently lacking "colony" theme - is viable. If anything, Civ V's "puppet city" mechanic come to mind.

You could also treat it as Empire 0 (British) vassalize Empire 1 (Haudenosaunee), Empire 1 changes culture to America around the time it breaks away from its liege. I know not all of those cultures line up exactly but mechanically this is the closest I can think of.
