I always kind of thought of myself as Neutral Good. I'm not a believer in rules for their own sake, but the good that comes from ignoring a rule should outweigh the harm incurred by surreptitiously changing the rules on everyone else. The most pernicious harms caused by breaking rules are the ones that aren't obvious, but rather confer an advantage to the parties that broke the rule that the rest of society can't easily detect, until those unscrupulous first movers have managed to roll the advantage up into a competitive moat.

I'm only commenting because I think it's interesting to think about why we think the things we do. I think it's a weird that anyone would want to fit an AD&D alignment onto me. :)
