I have not played this, being a PS3 user, but based on what I've read and the very few videos on Youtube, I'd have to say Dead Money is a reskin of Op: Anch. It gives cool looking loot and a fun story, but in the end, it's non repeatable, linear, and is a constant kill fest with a weapon of your choice. Now, this isn't to say it is a BAD DLC, because it certianly looks very fun, and I want to play it, but Dead Money seems to me to leave something to be desired, but I cannot quite place my thumb on what it is.
Add [censored] exploding collars and useless clouds of poison gas and it literally is just a reskin of O:A.
Hmm.
Pro's
Writing.
Characters.
Atmosphere.
Level design.
Difficulty.
Almost a weapon for each weapon class. (Explosives get that gas canister but they are like Bio-Gas from Point Lookout; limited.)
Ulysses info. :ahhh:
New toxic gas feature.
New chips exchange system.
Lengthy DLC. (It's [censored] huge! It took me 9 hours to complete (excluding smoke breaks, toilet visits and occasionally reading the forums for a minute or two.)
Con's
Can't return. (I liked roaming the streets in fear of the ghost people and the gas, what I hated about The Pitt was that I loved to fight the Trogs, but they didn't respawn which means I can only fight them once.)
The companions aren't permanent. (But I respect that, it's sad I couldn't bring DoGod back with me but I understand why I couldn't at the same time.
The exploration isn't rewarding enough. (Exploration is only good if there is good loot like uniques and stuff to find, if there isn't any, then exploration is pointless.)
Lengthy DLC. (While I like that it's long it also puts me off to complete it again, listen, in the wasteland I can do whatever I want to do, if I want to complete a quest, I can do so, if I just want to play Caravan, I can do so, if I just wants to kill stuff, I can do so, in Dead Money, I get clausterphobic, especially since I can't return once I've completed it. It means that I'm stuck in there for at least 6 hours.)
Ah, ok.

The DLC only took me 3-4 hours (including multiple deaths at the hands of the Collar, bathroom breaks, and a twenty minute snack). I also felt the writing was very unoriginal (really, a heist plot?). The only cool thing they added that was actually helpful was the gold bars, but too bad they weighed 35 pounds a piece AND only got you 5-10k caps.
The weapons were extremely limited, and you would find yourself using melee or unarmed weapons later on once you ran out of .357 bullets or gas bombs. The Ghost people weren't that dangerous either. They used weak weapons and couldn't take too much punishment. The Holograms were interesting at first, but then got annoying and pointless when you could easily slip by them. The collars made little sense in the DLC also, seeing as how
every single radio/speaker was tuned into the same exact frequency. The survival aspect was pretty neat, and would have been better if there weren't so many chips on the ground (I had 15+ stimpacks within forty minutes of starting the DLC). A variaty in enemies would have been nice too. How come there aren't any other humans running around except the Ghost people and your group? Why are there so many traps and Ghost people if there are no others? The Ghost people were just "there" to fight with no purpose.
