"Now this question has probably been asked before, but zombies have an expiration date. Eventually they will die off, starve from the lack of human flesh, or be so riddled with lead that they can't move anymore, but they will end. After the zombies are gone, what do you think the next biggest danger will be?
Roving bands of bandits causing pain and dismay were every they tread, diseases festering due to the mass casualties of the living and undead, the lack of a government or social structure, or some other devastation not listed?
What do you think the next hurdle would be to try to reestablish the old way of life or create a something new?"

"No, just no, Fallout 3 universe has no crops, working guns, livestock that survived and reproduced and the towns are still made of refuse 200 years after the bombs fall. The reason why they had to diverge the time line is so Science! could work and not regular science.

That said the next biggest danger, depending on your location will either be raiders or a diminishing food supply. Raiders will try looting what they can get from the city and suburbs, before heading out into the countryside.

And any plans for long term survival need to include agriculture, livestock, hunting and gathering and for all that you will either need a big "green" roof or move out to the countryside. Unless you would rather starve to death"

"You do know eating anything with a similar genetic code (i.e any person) to yourself makes you mentally impaired right?"

"As I've said before, I don't support cannibalism. It won't be allowed in my group if I can help it.

That being said, IMO, there are two kinds of cannibalism:
1. Eating an already-dead corpse. This isn't really THAT bad.
2. Killing someone in order to eat them. This just seems unthinkable to me."
