I have lived in five countries, only two of which are represented in Civ. I have lived in the second and twenty-second cities on the English list, though I currently live in neither. The city where I went to school is a City-State. My father's country (and the country in which I now live) is a major Civ; my mother's country is represented by a City-State - which is also the city in which she was born - and a Natural Wonder, which I have visited.
Neither the city nor the country in which I was born are, as far as I'm aware, represented in any way in Civ. Most people I know haven't even heard of it, though I suspect quite a few CivFanatics will have, being as they are a fairly well-informed bunch
ETA: oh, and my dad used to work for an organisation that is represented in the current iteration of Civ as a World Wonder!
