Multiple Personality GMing

As a GM, it’s a matter of course that I end up playing multiple NPCs in a single session.  And while I’ve been running games for a long time already, I have to confess that adequately playing an NPC is one of my personal weaknesses.  I have difficulty switching from character to character unless I’ve put a lot of thought and time into just how a given character thinks and acts.

That said, perhaps it will benefit me, and my readers if I outline just how I run NPCs in my games.  For the sake of consistency, we’ll use examples in the context of a supers game.
