No, Vegas was hsi brain child when it came to story concept, scope of the world, number of companions, etc. He was the lead director, not just the weapon balancer. He even designed specific characters. He was in charge of putting people in tasks that where planned out by him and the design team, it's not like Gonzales came up with the whole story of the game by himself and Sawyer left him just do whatever.
Okay, my mistake.
Still, doesn't change my opinion that seeing another quality Fallout title by Obsidian are very low.
