YOOO im baack guys, but my favorite dlc would prolly be Old World Blues, I get nostalgic evertime I think of it.

Point Lookout and Far Harbor. I just love the atmosphere in these too.

Dawnguard just to slay some more vampires and point lookout because it had cool enemies and awesome setting and atmosphere

I loved all the dlcs for Fallout 3, maybe a bit less the Point Lookout had a grate scene and zone but it lacked content in my opinion it seamed a bit empty some times

Shivering Isles for Elder Scrolls
Old World Blues for Fallout.

S.I is just so fucking rad man. I mean its beautiful nature and colorful creatures and flora, and the dark twisted swamps with its even more twisted inhabitants. And then you realise that these two very different lands converge into one giant map (and one town). The weapons are cool, the man himself is so funny and random (Clouds! Or was it clowns?), the story is interesting, the personalities are diverse, and the entire DLC feels like your playing two different worlds with how different S.I's inhabitants are. Whats not to love?

OWB is my Fallout choice just because I find it to be a tad better than HH. There is everything in OWB that screams 1950's B-movie Sci-fi. Robo scorpions, outragious villains, mad scientists, weird gadgets, and some unexpected insight into the man your hunting(Ulysses) and some background on an old friend. Also add points for the funny confused scientists, your brain and a mini securitron obssessed with cups and you got a pretty damn fine DLC. The main quest is pretty basic sure, but what makes OWB's great is that you get more enjoyment from exploring and discovering than you do from completing the main quest asap. Excellent cast voices as well. Walking Eyes anyone?

Thats this Zombies opinions.

For me it would have to be the Dragonborn DLC from Skyrim. I just liked the idea of being in a place so similar to Morrowind. Having the soundtrack from Morrowind was freaking awesome too though, never left Solstheim once I finished the quest now that I think about it actually (same can be said about Shivering Isles)..

I would also have to say Shivering Isles for Oblivion. The whole end game for the DLC was downright amazing. It had an awesome story line, an extremely beautiful landscape and the fact that you became a god in the end was just the icing on the cake.

Shivering Isles for the Elder Scrolls is undeniably one of the best DLCs ever. As for Fallout I would probably go with Old World Blues and Point Lookout.

Lonesome road, easily
Based on the other posts here, I feel I shouldn't voice my opinion on the FO3 DLC

The creepy ambient of The Pitt and Point Lookout

Spoiler:

Elderscrolls it has to be Shivering Isles for Oblivion and for Fallout its Point Lookout for FO3.

For me Point Lookout for FO3 and Lonesome Road for NV.

Shivering Isles followed by Dragonborn. Both added immense and interesting worldspaces and (especially SI) had some interesting characters. Not to mention what they added to TES lore.

I enjoyed all the New Vegas DLCs if NV is included.

But for actual Betehsda DLCs, gonna have to say Operation Anchorage and Point Lookout. Loved Op. Anchorage for the sole reason of getting a glimpse at how the Resources Wars went, albeit in a historically inaccurate manner since General Chase was full of himself. Point Lookout was pretty fun for the weapons it offered and a look at rivalries that refused to die, even after the Great War. They both can't hold a candle to what NV offered in terms of DLCs, but I felt they where solid attempts in Bethesda's part.

Im actually going to say Far Harbor. I just liked the enviroment and feel of the island + the fog made it a little more "spooky" and different. On the Fallout side Lonesome Road is my absolute favorite

For an actual Beth game, I'd go with Point Lookout. I loved the creepy vibe to the whole place, and that Confederate Hat had to be the only thing I wore on my head from that point on. I greatly enjoyed the "Walking with Spirits" quest. The grin on me face to see a similar quest in Far Harbour surprised me a bit.

As for Obsidian's New Vegas, would be Dead Money. I know, I know, let all that hate out. Boo me, I can take it. Joking about the usual dislike of it aside, I really enjoyed the change of pace. I went from being one the most hardcore wastelanders ever, capable of taking on everything the Legion and associates could throw at me, to being stripped of everything and forced to fight enemies that wouldn't die unless you tried extra hard and smashed them to bits with my extra favorite and extra pointy stick with kitchenware attached. I will forever and always miss Christine. Finally, I want to stab every radio I find after Dead Money. Every. Single. One. Hearing that beeping made me more terrified than anything else in the wastes.

For me it was Dead Money that takes the cake since it forced my me and my character to approach situations differently since we lacked any of our gear. Though the only reason it's my favorite, is the end when your in the vault and you cannot take everything with you without dying. It gave me a dilemma that no dlc has yet to match or place on me. "to loot, or to die horribly in some rich guys vault , that is the question"

I think I'll go with Shivering Isles for Oblivion, Dragonborn for Skyrim and Bloodmoon for Morrowind. These three addons uncover things about three Daedric Princes - Sheogorath, Hermaeus Mora and Hircine in a very interesting way. But the best one from these three to me is definitely Shivering Isles.

I suppose the pit in fallout 3 because it makes you work for you stuff i like the story and the atomoste really felt like a slave of labor there so i really liked it as for point lookout Maybe...but it has a lot of open nothing unlike something like shivering lsles for oblivion which feels like another game all by itself.

Dead money and honest hearts stand out to me Honest hearts because of the environment quest joshua, etc its great and Dead money same reason as the pitt but the characters....my god the characters...they are amazing. I will never forget christine.

So to answer the Topic Dead money no question. Everything a DLC should be.

Lonesome Road hands down, it's a clear example of how and why obsidian does better fallouts as the amount of hinting they have done of ulysses before any of the dlcs even came out were in the game was amazing. The hidden story behind your courier and your lost memory also made for a great twist when you finally realized your character wasn't just a normal run of the mill messenger. It just showed a great pace as it connected all the dlc together and the main game too.

i would have to say The Pitt. I like that i can be allied with the coolest group of Raiders.
