Continuing the theme of the fastest science victory and largest city threads, this one's about how to achieve the earliest cultural victory. You'd probably want to start in a coastal city next to loads of jungles and a desert tile with a mountain nearby. Then you can get the culture from jungles pantheon and build Petra, SOH, and Neuschwanstein. Playing as Siam would probably be best, with a bunch of Swedens about to speed up Great Artist generation. Allying with cultural city-states will fill have you popping policies very quickly, especially if you're only going to play with one city.
Of course there's always the method of playing a hotseat game against yourself and creating a huge empire to puppet, but that might require a bit too much time for the purpose of this experiment.
