In another interview in their Inside the Vault series, Bethesda Blog interviews Fallout: New Vegas senior artist Joe Sanabria. Here's an excerpt:
“What’s your job at Obsidian?
I’m a Senior Artist here at the studio, which is what they call you when you get gray hairs and have been doing this for a few years.
My job in a nutshell is to make Fallout: New Vegas look good. I focus on the visual development of the game and define the artistic direction.
What games have you worked on?
The first game I worked on was called the Neverhood Chronicles, a cool little PC title done entirely in clay. After that I worked on Skullmonkeys, which was a side scrolling platform game on the PS1. In addition to being one of the level designers, I was also a level boss named Joe Head Joe.”
