I don't know if I can trust my memory on this...but I will try.
Dwarves was not a try-hard grim dark setting. The dwarves themselves were not like, "Hi, I'm the great (x 10) ancestor of that ol'curmudgeon, Grumpy dwarf!" Instead, the dwarfs had certain themes that tied them to their (future) ancestor. For example, one of the dwarfs was a wild barbarian, and he was mute. Another one was a bard. I can't remember the rest of them... I have pictures of them somewhere - and as you look at them, you can see traces of who they are based on, like a facial expression, or the way they stand. It was subtle touches.
I don't believe Bethesda hates us, and we certainly don't hate them. While we created the content of New Vegas and the New Vegas DLC, it was their engine, their previous success with FO3, and their first class marketing that launched New Vegas to success. Without Bethesda, it would just be the Codex arguing over how New Vegas is either the best or the worst thing ever - and almost no one else.
That is the objective truth.
Subjectively, do I wish we had garnered more of the financial success? Of course, who wouldn't? On bad days do I feel myself a little bit salty about it? Of course, but that isn't healthy so instead I try to focus on how thankful we are that we even got to MAKE IT. Obsidian also got a lot of business opportunities because of New Vegas, and we owe that to Bethesda.
Everyone always brings up Backspace, I don't remember that EVER going anywhere other than pitches and maybe Jason Fader doing some early prototyping, but I could be wrong. I do think it was a cool pitch and hopefully someday either Obsidian or Jason will get to do something with it.
bah, I got interrupted and lost my train of thought.
