I dont know which category this goes in but in Fallout NV when you see those caravans or people that were always selling items and are walking around they have around 1,000 to 10,000 caps. in fallout 3 when you killed a caravan/person you might get some bad karma but you were able to steal all the items that that carvan or person had. In NV when you kill some one there stuff dissapeared and you could not rob them, which became ultimately pointless. Hell if i went inside a base or town in NV killed everyone in there i should be able to have access to all items and weapons/money/armor and anything of value inside that location.
More Weapon Vaults, Stashes.
Will post more soon
