Why not make a "Human stronghold" that players should find/reach. Bandits would not be allowed to enter. Here you could stock up( exchange items). From here you could go on a mission.For example to bring back car parts or maybe bloodbags etc... or form a group and go after bandits or go find survivors and help them. Because now as you all are saying it's kinda boring, you go looting, you eat, drink and then you go loot a little more. And it sucks when everyone SOS(shoots on sight). Just my thoughts. In the end it should be like free the world from zombies.
