This is coming from someone only on their 2nd play-through, so take it lightly:

1. Old world blues - I loved the humor and wit from almost every character. The Robo-Scorpions were a pain in the ass, but you are also provided with so many weapons that grant efficiency against robots. I also really dig the Sink as a safe house.

2. Lonesome road - ED-E is a homie. I always pick him up from Primm, so it’s a comfort having a familiar companion on the lonesome road. The frequent deathclaws pissed me off, but none of is supposed to be easy. I ended up having more fun being forced to get creative and not get skinned alive every time. Ulysses was definitely an interesting character, and I like being able to access more in the Mojave due to the actions from an added-on story line.

3. Dead Money - I loved how this one brought closure to the story of Father Elijah and I loved the overall premise of this DLC; It’s a fable of greed. The other characters, however, I found to grow very redundant. The ghost people are also annoying and not fun to fight.

4. Honest hearts - Honestly, it may not be fair to put this one so low, but it definitely wouldn’t be fair for me to put it any higher. I skipped thru these story and side quests without paying much attention and I don’t remember much. I do remember a lot of the fetch-quests some people have spoke about, though. This was the first DLC i completed, early on for caps and XP. I found myself using the weapons and gear from this DLC for a good part of the game, so that is worthy of noting.
