When I'm forced to take an alignment, I generally go with chaotic good; tending to do what's right and, like, totally not caring for what the Man says about it, dude.
I've never been a fan of alignment. It never really works in PnP, leading to arguments about what is and isn't keeping with your alignment, intent vs. results, etc., and it's even worse in CRGPs. It usually boils down to super goody-two-shoes or an adolescent's idea of an uber-cool, selfish, short-sighted jackass and often feels crammed in. It's another one of those pieces of baggage that we can't seem to stop lugging around with us. Hmmm... I might have an idea for another thread.
