Point blank, my "world" is the actual real world, but it's set in the distant future -- technology isn't even a major player, society has almost torn itself down. My story is set in one county, a real county in NY. Here's the thing, my story takes place ONLY in this county, so far. The focus is basically Oneida County, NY. The story's name itself refers to the city of Rome, New York. My question is this, is it a good or bad idea to leave the rest of the world out of the story, when whatever is happening is effecting, essentially, the entire world? SHOULD I include like the other Americas, Europe, etc.? Would it feel like a hollow or implausible story if I ignored all other areas? I might mention other parts of the US at some point(s), we'll see. I might make my characters chase each other around the ruined United States hah.
