I've lived in Izmir all of my life and love the city. I wish that the Greek, Jewish, Armenian etc. population of the city didn't have to leave the city and we could live together but It isn't fair to say that Turks burnt the city down.
If you ever want to do a part two for cities or add more, id recommend that one, and also Frederikstadt renamed to João Pessoa, same context as the Recife one.
And perhaps not in some, but in most cases with that intention from the start. Places are called after/in honor of existing places, not (usualy) the exact same name. Especially in cases of newly conquered/explored land.
"I hereby declare these lands, New Jetpunk!"
towns later established and/or playing a less important role in the settling often do have simple copies of names.
