Thank you. 

That would imply that not only the name, it sounds like the concept of evolving one civ into another. I have that feeling.

I think it could be done in public mod assets rather than requiring touching the C++ code. 

That's definitely beyond a mod.

Yes! That is I want to do.

The man wants to change the civilization name dynamically. For example, if he's playing "Celts", he'd like to become either "Britons" or "Gauls" once he reaches a new phase, or researches some technology. This is kinda tricky to do. There were concepts of this in the early discussions, but the team decided for more distinct civilizations instead of playable "factions" within the existing civilizations.

Write your question in Spanish and we'll try to understand it from there.
