Why wouldn't you right? You're passing up so much loot if you don't!
But yeah, I'm an obsessive packrat in those games, pick up anything not nailed down/not considered stealing. So you know I write down the locations of any locked stuff beyond my level to go back and get it later, even if it's just a lunchbox or some shit lol.
But what if I need even more money later? I'm just sure there'll be something I want to spend it on at some point. And so I better just keep grabbing all these forks and spoons to sell...
