My problem with Obsidian's games is not that they don't finish them properly (although that is a problem). My problem is the air of pretension that surrounds their games. You can just tell that they think they are so much smarter than the people who made the first game, and the people who liked it. The smugness just rolls through their dialogue. Fallout: New Vegas managed to avoid that for the most part, but it crept in at times (especially in the Divide DLC

).
That's fair. I love New Vegas, but I did feel a lot like I was being talked down on with the Lonesome Road DLC, which is the main reason I wasn't a huge fan of it. It's like, having showed us the themes they wanted to impart throughout the base game, they then decided that we were not smart enough to get them and spelled everything out for us. Ulysses just generally came across (to me) as an existential buffoon, a first-year philosophy student who says 'sheeple' unironically and is convinced that his insights are, like, totally unique and deep, man. This wouldn't be a huge problem, except that Ulysses is clearly intended to be an author avatar, which are never not annoying, even when the author is talented (see: Heinlein in Starship Troopers, Richard Morgan in the final Takeshi Kovacs book).
[censored]ing South Park. I'm not a fan of it at all and hence have no interest in The Stick of Truth, but I really want it to at least succeed so that Obsidian can make something truly amazing in the near future. So now I'm in a precarious position; do I really want to pay for a product I don't want just to help them along?
Yeah, I love South Park but I don't see how the appeal could transfer to a game, when biting satire and comic timing are what's good about the show.
I think that some people were also disappointed by New Vegas not because of the bugs, but because it wasn't the Bethesda style sandboxy dungeon crawler which they expected after Fallout 3.
I think this hits the nail on the head. Aside from (kind of) sharing a universe, an engine and gameplay, they are just completely different games, if that makes sense. If you approach both the same way you're going to be disappointed in at least one.
