Personally I would love some "PVE" Servers, not like the players are invincible for other players, more like a mentality. The only thing I would add as an option for servers (if I could) is a bounty for bandits (general position automatically written in chat, marked on the map with possible exceptions for certain areas like the military bases and airstrips, etc.) - this way players who are inclined to hunt those bandits (hrm, heroes) would have it easier, the bandits harder and normal survivors could escape (or die trying to become a hero :)).
