My point being that there needs to be more flavor to the world. Whether its raiders ruling an area, a merc company using some small farm settlements as a source of supplies, or the successors to a prewar gang running a protection racket in an bombed out neighborhood. They don't need to be that smart, just lazy. Extorting locals for food is easier than raiding. Even gangs have ways to supply drugs and other things to sell, they don't just steal things to sell from people who make them, they work with them. It makes sense that there would be some raiders, whether they are clans with some unique flare or generic pyros like they currently are in some locations, but not everywhere. This would give the world at least some depth that is currently gone. Hell even in Oblivion, they gave the downs different architecture, giving 25 "raider" factions a different paint job wouldn't be difficult.
