Filmdeg Miniatures is a YouTube channel run by Tom Evans that is full of interviews with gaming luminaries. I know it mainly for unearthing Warhammer history on topics like the early editions of Warhammer Fantasy Battle. Evans also covers videogames, most recently in an eight-hour oral history of Morrowind in which he lets a host of the classic weird-fantasy RPG's creators meander up and down memory lane as they discuss how it was made.
One enlightening subject is writer and quest designer Mark Nelson, who was responsible for a chunk of Morrowind's expansions, Tribunal and Bloodmoon, as well as fleshing out the starter village of Seyda Neen. He's the guy responsible for Tarhiel, the wizard who memorably falls out of the sky in front of you the moment you leave, for instance.
