Empyreus said:The more I read this the more I have to question, like half the other people posting, why this is such an issue for you.
Answering for myself:
I don't run adventures set in society rather than in dungeons: mysteries and intrigues rather than dungeon raids. That being the case, individual motivations are more use to me in constructing adventures than races are, and the side people take in the war between the alignments. In my adventures it is often important for the characters to work out or guess what an NPC's motivation is. The more possible motivations the NPCs might have, the more options I have in adventure design.
For instance, in my current campaign the PCs are working for an able and honest magistrate who is trying to rid Thekla (a major city) of violent crime (Barminian). He was for nineteen years a member of an elite military unit (modelled on the Sacred Band of Thebes) that consists of couples of male lovers. But he got his current job because he married a grand-daughter of the Emperor (Princess Rani). She, until her marriage, was in love with a handsome and gallant youngster, a member of the Hundred Youths (Arpad).
The campaign is a political intrigue complicated by romantic motivations. It is far more important that Barminian might be gay and Rani in a loveless marriage than what rooms open off the Warriors' Hall in the official palace of the Metropolitan Prefect of Thekla.
