I mean some like hyperdense megacities and everything that comes with it bleeding edge/underground scene for X, 24 hours life, close proximity to people. It's completely alien to me as well but why look down on people liking different things?
It's interesting. I live in London UK, which some might think of as a megacity - though when I look at the biggest cities in the orient (Singapore, Shenzhen etc) London feels like Hobbiton in comparison. I suppose what you're used to becomes your "zero line", and one inevitably assesses other places relative to that.
