Tell us a little about your role in the making of Fallout 1/2/3 (Van Buren)/Tactics ?

I had nothing to do with the creation of Fallout 1 or 2. For Fallout 3 I started out as a designer when they cancelled Jefferson. Eventually JE Sawyer was so impressed with my phat ping-pong skills that he made me lead story designer for the game, which let him focus on the technical aspects (interface, game mechanics, etc.). As story lead I managed the overall story and continuity, wrote several areas, and beat the other designers into submission with my special Fallout ping-pong paddle, nicknamed "Duck and Cover."

What were you favourite places in fallout and why?

For not capitalizing "Fallout" in the above sentence, you should be punished. You're no fan!
The Necropolis was damn creepy. The Cathedral was, too, mainly because of those damn TV sets and the weird cultists everywhere. I liked Junktown, though I never really felt a strong incentive to befriend that fat bastard Gizmo. I liked the parts where you learned a lot of history (whether world history or personal campaign-relevant history, such as the exploration of the Glow by the paladins or the notes on the FEV research).​
