Dead Money was so bad that (despite owning all of the DLC) after I beat it I stopped playing and haven't went back. Now I'm debating firing it up again.
I'm playing Dead Money right now and I don't see what's so bad about it. I haven't gotten in to the casino yet, though. I'm still putting the 3 into position for the gala event.
Of course, I'm also level 30 and had focused on melee & guns as far as perks and fighting abilities. The ability to wtfpwn the inhabitants has made it pretty easy so far.
How much Dead Money sucks is half dependent on your tolerance for the collar/radio gimmick and half on your skillset. Melee, Energy Weapons, or Sneak? You're golden, especially with two out of the three. But if you're like me who did it with Explosives, Repair, and Science as tags? Have fun killing
anything while also having to deal with the stupid radio bullshit.
After two of the hubs I finally got fed up with it and "cheated"; I crafted up a teleporter to the mod-added Underground Hideout using materials I found lying around the casino and hopped back to grab some of my older equipment, like my old grenade launcher. That made it
much more tolerable and I only half consider it cheating since I used materials I found on my own.
