A short developer diary addition from New Vegas project lead J.E. Sawyer talks about NavMeshes and how games are large projects, while public credit gets overly focused on a handful of people.
I enjoy talking about our work and I have the good fortune to be able to do so to the press and fans, but I worry that it obfuscates the immense volume of human time, headaches, frustration, and creative passion that goes into making something of this scale. This is not the result of one person's ideas, the fruit of one person's labor. And though the press and fans have emphasized the connection between the Obsidian of today and Black Isle of days gone by, I believe it diminishes the role of both Bethesda, in developing Fallout 3, and the myriad developers at Obsidian who are coming to Fallout for the first time. Without their creativity and drive, this game could never have been made.
