Oh boy. glad someone made this topic finally!
I'm just going to talk about the DLCs in order, as to avoid confusion.
Operation Anchorage:
6/10This DLC was cool when I played it, but now I only really play it so I can do the glitch to get the winterized Combat armor and Winterized weapons (If you put gary's corpse in the chair before you enter the simulation, when you begin to exit the simulation, go into first person, and rapidly tap E. If you did it right, you should activate Gary's inventory. Dump your items into there, then exit his body, then get the DLC gear from his corpse!). The "Plot twist" at the end was poorly written, and I really avoid this DLC most of the time.
The Pitt:
8/10I loved the Pitt. It was very entertaining, and had great replay value in my opinion, and the landscape was a gem on its own. I love it when Fallout games have locations that have more character then some of the NPCs. I actually felt the need to survive whenever I entered the Pitt as a slave. Finding the hidden cashes of supplies was great. All in all, a great DLC, but once you beat it, there's really nothing to do afterwords, except for use the ammo press.
Broken Steel:
9/10The name just sounds awesome. Everyone pretty much loves this DLC, because it does what the campaign should have done: let you play after the ending!
The new weapons were well-distributed around the Capital Wasteland, the new Hellfire armor was unbelievably BADASS, and the tesla cannon was great for killing those pesky Enclave Vertibirds. Having Sarah Lyons eventually evolve into a friend instead of an ally was really rewarding, and Father Lyons sort of turned into a father-figure for me. My only problems with this DLC were centered around the death of Liberty Prime. I was so shocked by his death, I threw my controller across the room while screaming,"NOOOOOO".
I had never been so mad at fallout before. Also, fetching cameras to help rebuild him, even though you knew he was NEVER going to walk again, was heartbreaking, Bethesda. Shame on you!
but really, the new wateland critters were fun and difficult. My only problem with this DLC was the fact that Three Dog talks about the battle for Project Purity even if you start a new game.
Point Lookout:
9/10As I've said, this DLC tied Broken Steel for my favorite. The swamp people were hilarious and dangerous, all at the same time. Their deaths by my grenades sent me rolling on the floor, laughing hysterically at a hillbilly screaming about his moonshine as I blasted him to bits. The NPCs in this DLC were worthwhile, and I actually began to see Desmond as less of an old coot, and more of an old, grumpy uncle. His battle with the brain was dramatic, and I can't tell you how many times his traps killed me. The first fight at Clavert Mansion was scary, and fun at the same time. Falling through the floor wasn't fun though.
But seriously, the side-quests were great. I enjoyed the landscape as well all in all, a good DLC, with plenty of replay value, even if it is just to try and save those rich wastelanders in that ghoul hunting expo.
Mothership Zeta:
4/10Oh god, where to start.... Mothership Zeta was, quite frankly, horrible. I didn't enjoy it at all. They just ran with a horrible gimmick, ruined a beautiful easter-egg, and wasted my time with all of the useless alien weapons and stupid NPCs. I did enjoy the samurai armor a bit, but I still think that Bethesda's time should have been spent on better things.
Now, New Vegas DLCs.
Dead Money:
8/10I actually enjoyed this DLC on my first playthrough. Maybe it's because it was the first New Vegas DLC to be released, but the horror atmosphere was enriching and totally believable. I found myself mourning the death of Frederick Sinclair. The man was so blinded by love and rage, he spent his entire fortune to build an impenetrable prison for the woman who betrayed him. You can actually find his body in the vault, having fallen onto steel pipes, ending his miserable life of regret and sadness, for he just couldn't let go of the woman he loved.
I grew to hate Dean Domino, his twisted ways, manipulating Vera to trick Sinclair, only because he thought Sinclair was too full of himself! He never wanted the money in the vault, he just wanted to hurt Sinclair, to leave him with nothing. The dark place that Dean calls his heart only changes if the Courier can convince him to be partners, not enemies. When I saw the quest through, the happiest moment for me was seeing the ending slide for Dean, showing that he had truly "Let Go"
Dog/God was my friend, and my enemy. I constantly battled with God until the ending. I feel like the ending of God/Dog was very linear. They either kill you and themselves, or you save them. I really didn't like the aspect of the shattered self that Obsidian represented in Dog/God. I feel the DLC could have been made without him.
Christine is the true embodiment of a dedicated soldier. She took this mission to hunt down Elijah because it was her duty to serve, but it soon evolved into a fit of rage, only wanting revenge on the man that caused her so much pain. Even though she couldn't speak n the beginning, I could tell how much she hated Elijah. Later, her voice actor was very believable, and I feel that it fit her character perfectly, even though she never would have had it if Dean hadn't damaged her so badly (Dean was the one who put her in the Auto-doc).
All in all, the central message of Dead Money was very well-written, I just don't think it had very much replay value. Along with all of the glitches, maybe the Obsidian team was just too overworked?
Honest Hearts:
9/10
This DLC is the true embodiment of hate and revenge. Joshua Graham, the Burned Man, is so full of hatred for the White Legs because they slaughtered New Canaan, that he is blind to how much he's changed the tribes of Zion. Daniel wants to run away to spare the Sorrows the horrors of battle, yet he does not see that the scourge of the white-legs must be stopped. I've only sided with Daniel once, and I hated it. I side with Joshua, but at the end I show him that he doesn't need to kill Salt-Upon-Wounds. The ending is much more rewarding. The worldspace for Honest Hearts is beautiful, but feels rushed. Still a good DLC though.
Old World Blues:
8/10I LOVED this DLC the first time I played it. The cooky gadgets in the Big MT, the experiments running amok, and how disconnected the scientists were from reality, showed how dangerous technology can truly be. My only complaint was having no companions, and how impossibly difficult the Robo-Scorpions were for me. Seriously! I wasted 1000 whole 5mm rounds on ONE. Jesus people, lower the health a little bit!
But seriously, a great DLC. I feel like the transportoplonder was kind on stupid. Why not just use a train? Oh, right...FATHER ELIJAH DESTROYED THEM ALL.
Anyway, the hints to future and past DLCs was fun and interesting. I perfer Christine's Vera Keyes voice over the one she has in the Big MT recorders.
Lonesome Road
7/10This DLC was....ok? I feel like the conclusion of the Ulysses story was forced. I didn't want to nuke anyone, but that would mean the death of Ed-E. The only real reason I like this DLC is for the landscape. The new armor and enemies are cool to, but the new weapons are, well, stupid. I never used them. I sometimes just skip this DLC, because I don't really care.
And there you have it! If you were just like "Tl;DR" Here's the verdict:
Favorite FO3 DLC: Broken Steel/Point Lookout
Favorite NV DLC: Honest Hearts
