I think it is fair and reasonable to critique the work that I have done/continue to do, but I do want to clarify the work I (and others) have done and have not done.
I did not have anything to do with the development of the story in NWN2. I came to Obsidian in July of 2005, long after the story had been established. In the capacity of a senior area designer, my only story contribution was to suggest and work through ideas about the background of the King of Shadows with George Ziets.
John Gonzalez developed the story for F:NV. Eric Fenstermaker developed the story for PoE. George Ziets developed the story for Mask of the Betrayer. I was the director of F:NV and PoE. Kevin Saunders was the lead designer (we didn't have directors then) on Mask of the Betrayer.
Writing on projects is split between multiple designers. E.g. on F:NV, over ten designers wrote quest and companion dialogue. I designed all of the main F:NV companions, but the actual writing was split up across many designers. Eric Fenstermaker wrote Boone, Travis Stout wrote Raul, John Gonzalez wrote Lily, Chris Avellone wrote Cass, Akil Hooper wrote ED-E's bleeps, Jesse wrote Rex, and I wrote Arcade. Writing was similarly split on Mask and PoE, but to clarify, I wrote no dialogue on Mask and only Pallegina and a few (~3) minor characters in PoE.
