I like the companions in New Vegas’ Dead Money DLC. But we don’t get enough time with each.
And Dog/God got screwed in the weapons department. To paraphrase the wiki: ‘Being a super mutant means, due to a quirk with the game engine, Dog/God is limited in the weapons his character model is able to hold. And because you can’t bring weapons into the Sierra Madre this means there’s only one weapon he’s able to equip in the entire DLC. And there’s only one that exists is in a optional area, only available right before you lose your companions for good, in the opposite direction where you’re supposed to take Dog/God, and he won’t have much time to use it anyway. And the sledgehammer won’t increase his attack power much to begin with.’
