Points of Light as a setting idea always crops up from time to time and D&D 4E heavily advertised with it. But what always bugged me with that is how it ignores how much interconnected infrastructure (to avoid the term civilization) is required to achieve something like the default technological level in D&D.

I was running a
Deadlands: Hell on Earth (post apocalyptic future) set in the remains of Little Rock, Arkansas and one of my players started asking questions about the vital statistics of the settlement. What was the population, how many were men, how many were women, how many children, how many households, how many mutants, and so on and so forth. As I answered each question, the look of realization dawned on her face and she asked, "You're just making this all up right now!" And it was the truth. Other than having a rough estimate of the total population, I didn't give any more thought to the demographic makeup because it didn't matter to me. Perhaps if we were playing futuristic census takers in a post apocalyptic world I would have paid more attention.
My use of the theme from
Mystery Science Theater 3000 up there is tongue-in-cheek. There's nothing wrong with building a world that might actually work in real life. Personally, I'm much more concerned with creating a world with a ton of adventure hooks and cool things to do and I don't worry overly much about things like where the city gets food, who do they trade with, what are the demographics, etc., etc. Unless those things are going to come into play during an adventure. All I require is a little verisimilitude and I'm fine.
