Vaguely related but there is this whole set of videos on the production of the Ultima series on Youtube by Majuular that I've been playing while working out. Just such a different time, I almost regret missing it.

His video on 7 and serpent's isle brought back a lot of memories (although my preferred origin game was Wing Commander)

The one on Ultima Underworld is my favourite. What an incredible game, so ahead of its time.
