Sir Walter Raleigh's settlers lasted 2 years before they were nearly wiped out, but that wasn't because of warlords, homeless food bandits or poor WiFi.  Their demise came because of being in unfamiliar weather conditions, harsh ecological conditions (spiders, snakes), disease, fever, frequent encounters with hostile natives (and evil dead vampires from the black sailed ship The Osiris)
