I would join this if Symphony D would allow if only to prove to someone that their low opinion of me is unworthy.
Sadly the people in the modern world (as in, today) who have the best chance of survival are militant extremists (who have large, well-armed, and well-prepared compounds in remote locations), or religious fundamentalists (such as the Amish, or some sects of Mennonites or Mormons) who similarly are highly self-sufficient and also generally located in more remote areas. A few unique environments (like, say, the New York underground) also permit interesting options, either for players or NPCs
It's possible, though not exactly probable, that a similar construction boom will occur before the events herein, although I feel that's somewhat unlikely as most people regard nuclear war as generally not survivable (and even if you somehow did, you probably wouldn't want to).
