Could be from a game, book, TV series, etc. What fictional world do you wish you could live in or at least experience? There'd probably be a few for me if I had to really think about it but one that sticks out to me the most is "Rapture" from Bioshock. It's a kind-of-horror/action-adventure video game I used to play all the time back in the day. It's a giant underwater city that was built in the 1940s , deep in the ocean to the west of Iceland that was created by a businessman who sought out a society free from government control and religion. It was basically an anarcho-capitalist society and in the video game you end up experiencing the city after a civil war breaks out from the lack of stability.

To put it simply, science wasn't being regulated and people were exploited into buying drugs to the point that everybody was whacked out of their mind. People were turned into drug addicts and the city fell apart. Having said that I'd have liked to experience what Rapture was like prior to the civil war.
