I know you can take it that way now, and you can make most things work one way or another, which I admire about the system.
But I liked it when it was a kind of separate thing, when it was separate from a psychological quirk. Like, "I'm claustrophobic, and that's from my childhood. But I have to find this guy and bring him to justice because I said I would."
I know "because I said I would" is a Psych thing. But I liked the heroic feeling that Duty was somehow quite separate from being a little loopy.
It's semantics in a sense, but I'm waxing nostalgiac here, not quibbling. Or maybe I'm doing both.
PS: You could argue that a Hunted is in some way a Psych Complication, because you obviously rubbed the guy (or gal) the wrong way with your personality. Psych Limit: Rubs people the wrong way to the point they want to kill him.
I guess I'd like to see "Duty/Honor/Tradition" as a separate category. Code vs. Killing etc.
