So, in the game, you get a player camp that can contain containers, which can contain a limited amount of loot. That becomes constraining, quickly.

You can carry as much as you want yourself, but it will burden you beyond a different point. Some of the most-important perks are based around increasing carry limits of different sorts of items. And you can respec at will after a couple levels, and some of that entails specing for being able to carry particular items.

So, in that game, Bethesda mostly sells cosmetic stuff.

They also sell some minor aid stuff, but one of the largest benefits one can buy is a container that can contain an unlimited amount of scrap.

Basically, if you want to buy anything, you can pay for pretty stuff that act as decorations or skins on your armor/items, pay for some minor help stuff, or pay for reducing the annoyance of inventory management.

In older games in the series, you could always at least store as much as you wanted in a container somewhere.

So if inventory management drives you nuts, 76 is probably gonna annoy you.
