Veteran computer RPG designer, responsible for Ultima Underworld 1&2, System Shock, Shadowcaster, Cybermage and Deus Ex among others. Has reputedly never written a line of code (at least, in the production of any of his games). Spector's games are notable for the emphasis on character development, consistent environments, as well as traditional paper RPG elements and storytelling.

There is an excellent old interview with him here, full of interesting facts about his work on the Ultima series : http://www.denmarkwa.net.au/~dantec/profile2.htm
