Feature request: the City-state "Manila" be renamed to "Maynila" about unciv HOT 1 CLOSED

Changing a civ name will break existing games, since that's also the id of that civ - so cities and units belonging to Manila will not find who they belong to
There's no problem changing city names etc, since those are purely cosmetic - and there's also no problem if a civ has a city in the same name as another civ, as you're describing here.
TL;DR I see your point, but the detrimental effects would far outweigh the slight historical inaccuracy we have here, so I'm politely declining this change :)

What's more is that this is the Civ V name for it.

You are of course welcome to change this in mods

from unciv.
