I have thousands of Sierra Madre chips and I'll still try and lug that scrap metal away with me so I can theoretically build a few more Repair Kits that I'll never use. It does not matter that I have running water from every base location and safehouse or a few dozen RadAways. Do I have 30 Purified Waters? Man I am taking that shit with me out of Dead Money.
Compound this with the fact that I always play hardcore and inventory management really does matter. But as a well-conditioned gamer, I'm a kleptomaniacal completionist that has to loot everything even vaguely useful. I take perverse pleasure in the crafting content OWB offers, but paradoxically, I hate micromanaging my inventory, especially through all the damn menus of the Pipboy. The speakers were not that frustrating to me except in 'final dungeon' leading up to the gold vault and even that was not a dealbreaker. Part of it is that I was much less of a Hoardy MacHoarderson and just kept my baggage light.
Some of it, I think, is that I was rushing through the content a bit much to really just enjoy it. I admit that I've enjoyed Dead Money more on a repeat playthrough.
