I really like this idea. I looked into Dead Linger which I think you could integrate into the quote. Therefore new "towns" would start. There are more twists to it. You would acctually have to form groups and clans to protect and loot enough stuff in order to build it. On the other side there would be no need in server hopping since the fort/town/whatever you want to call it, will only stay with that server. I think it is a great idea.
