The writing for Joshua Graham and the Survivalist was really satisfying.
[spoiler:9700f962a9]Graham really exuded pure, fearless charisma from the beginning. The reverence of the Dead Horses to him rubbed off right away. I agree that the final mission was kind of weird, but it was badass running across Zion with Graham, picking people off in an all-out war. Let's see...I felt Daniel was kind of undercharacterized. He needed more backstory for his pacifism. With Graham's charisma, I'm guessing a lot of people are going to just default to defending Zion (it also seems to make more sense offhand). Honestly, Graham was so totally badass that the first time through, I raised no objections to executing Salt upon the Wounds. I stuck with pardoning him as my chosen ending, since for all of Graham's badassery (and the unbelievably coolness of the burning fires within him metaphor), I wanted him to have some peace. Trading with him and having him fix your stuff made him immediately accessible and added to his charisma early on.
I didn't mind the bizarre topography, except when it confused the hell out of companions and made them get lost for 5 minutes at a time. I brought an AM rifle from the Mojave, and had a lot of fun with it sniping from cliffsides. There was also a brilliant moment when dealing with the bridge traps; I perched on a cliffside and rained down Archimedes upon 3 White Legs. The other beasts were decently difficult, though I remember cursing audibly the first time I saw a cazador (like really? these fucking things are here, too?). The spore creatures were kind of a joke, though; the Venus Flytrap things were barely a threat.
The overall ambience was pretty cool; I loved the slot canyons, especially that initial approach to Dead Horses Point. By the time you see the Three Marys, though, the "holy fuck whoa" is kind of worn off. Makes me wish the final battle area would have had some kind of new gimmick. I also couldn't believe that more unique weapons/armor weren't included compared to Dead Money, which seemed to have a few more new weapons. I love the .45 pistol and rifle, though.[/spoiler:9700f962a9]
Ultimately, I feel like I explored 75% of the locations, and hashed out everything in a solid 7 hour session. Dead Money took longer, I think. I'm really excited for Lonesome Road, the way the Divide is being pumped up...
Edit:
Here's a nice memento from the journey.
