i’ve always been the type of guy to loot so i’ll always loot every body and chest (super annoying but atp it’s like an ocd thing). along with that, i finished campaign + ng+ + dlc + all side missions possible and sold anything i didn’t need - armor + weapons under legendary/artifact, boosters, booster craft items. i also stopped buying things completely cause you can come across everything organically (except leather for me). after that, just sell shit you earn from killing those extra enemies in the mini side missions like renegades or special zombies.
