I've been following his work since Fallout 3 came out and it is dare I say the best designed game to come out in the second part of the last decade. I felt devastated when I learned of his death. He was an absolutely brilliant concept designer. The stuff that he did for fallout was borderline genius. Many have tried but he managed to perfectly capture the spirit of the 50s retro-futurism without making it feel dated or banal. May he rest in peace.
