You want to live in a house? Sure, why not. Store all your crap in it, whatever. Lots of containers to store your guns, gold bars, teddy bears, tin cans, lingerie, burnt books, alcohol, whatever it is that you hoard. Also a super sekrit storage room full of respawning ammo boxes with 1000 rounds in each of them. And some of the better uniques. It's completely optional if you want to be a godmode turbomurder slayer of all. Or not. I dunno.
