i reckon resources should be much rarer, more dangerous to obtain. There should be a random chance of having resources, and you cant re-enter the same area, need to move at least a bit. Should probably have a higher encounter chance the more you wander around a small area(attracting attention? or just other scavengers out to get same resources). If there wasnt so much resources around there wouldnt be like a hojjillion bbs around, and players would need to trade among themselves. Just my opinion, with no idea how hard to implement this is and with very little game experience.
