[Gandhi one-city cultural victory story]
That's very close to how I played my second game. Whenever I think of attempting a one-city challenge, I always go straight to Gandhi - in Civ V they practically make this a no-brainer. I never had any significant military development, and avoided war for the entire game.
My strategy was pretty much like yours, building wonder after wonder. I also took a lot of time to ally with neighboring city-states, gaining the favor of at least four at any given time. Two of those city-states were militaristic, one was maritime and the final one was a cultural city-state. If there were more cultural ones, I would have gone for that so I could have won much sooner!
Siam and Egypt became the dominant world powers, fighting a bloody 500 year war against one another until Egypt finally fell around 1900 AD. There was one moment when Ramkhamhaeng was attacking an allied city-state, and instead of risking war with him, I asked what he wanted for 30 turns of peace for Oslo, and he just said he was fine with that. He even came back and
apologized for attacking my ally on the next turn! It was hilarious, especially since he could have rolled over my country at any time - I was dependent on Oslo and Hanoi for my military!
A human opponent would have steamrolled over me at the end, but then again, maybe not. I didn't have very many points and I let my open border agreements lapse with Siam and positioned all four of my military units on my frontiers. They could have calculated that I have built up quite an army, though this was far from the truth.
