The Palladium Books games had really useful Alignment descriptors, that map pretty well to D&D alignments. I used to hand these out to my players, and it avoided countless hours of arguments.
Principled - Lawful Good
Scrupulous - Chaotic Good
Unprincipled - Neutral Good (several bits are easily flipped to map to Neutral Evil)
Anarchist - Chaotic Neutral
Diabolic - Chaotic Evil
Aberrant - Lawful Evil
This page repeats the Palladium Books text verbatim, and is cheaper than buying the books. (Although, seriously, Rifts - is good gonzo fun, despite the game mechanics being a hot mess.)
(Savage Rifts is a licensed adaptation of the game setting, with a much cleaner game system underneath. It presents a very different experience, not being a hot mess, but it's a lot more playable, too.)
