If there's one thing that's been warming my heart lately on these forums, it's that for the past few months, Dead Money has been seeing a lot more love than ever before. Is it because the haters have finally shut up, or because many are really beginning to see its intrinsic value? I really hope it's the latter.
Makes me hope that in the future, not only will New Vegas be more fondly remembered than most other Bethesda-esque RPGs of this generation, but that among its DLCs, DM will be considered a well thought-out and brilliantly designed expansion that everything else should aspire to.
It's more likely the haters have left. I think Dead Money is the type of thing where if they didn't like it the first time, they're not gonna be willing to try it a second time. You're also kinda ruining Dead Money's experience once you learn to remember where everything is. I mean let's be honest, as amazing as it can be your first playthrough, it falls flat on replay-value in some ways.
I'm fully confident that New Vegas will be remembered more fondly than FO3 or Skyrim though and will withstand the test of time better. Hell I expect Skyrim to die in the dust the moment TES 6 is released. As I've always said, a good game can last you a year or two, a good story can last you a lifetime.
I wished there was an ACTUAL reason how the collar was removed at the end. It was just... gone.
Elijah loses his signal to your collar; the collar won't work between floors. I've always assumed that with that, the Courier was simply able to mess around with it and get it off. Christine will tell you (if you tick her off) that she'd been testing with it when given a chance, to understand how it works and figure out how to remove it. By the time you find her I think she says she's "almost got it figured out" but hasn't quite yet. Bomb collars have also been removed before, for example the Lone Wanderer can remove the CW versions without needing a skill check sometimes, iirc, and the slaves at Cottonwood cove can be freed if you have the skill.
The real issue is that if you've got a 2 INT Courier with no skill in Science or Explosives, but yeah I'd imagine it would tick a lot of people off if they completed Dead Money and then it said "your character died anyways because he killed Christine and he's too much of a [censored] to remove the collar himself."
