Alignment: This is the first thing I went to, given the controversy that's been swirling around it. First off: IT IS NOT A LINEAR SYSTEM--at least, no more than the old 3x3 grid. The alignments are listed in this order: Good, Lawful Good, Evil, Chaotic Evil, Unaligned. The definitions for Lawful Good and Chaotic Evil are very much what we are familiar with, and Good and Evil are similar to Neutral Good and Neutral Evil. The difference between Good and Lawful Good is that LG characters tend to think more about order and social structure, and while they recognize that authority figures can be corrupt and laws can be evil, they prefer to work within the system. Good characters can work with authority, but recognize that power tends to corrupt. The two alignments get along pretty well, but good characters think lawful good characters think too much about order and not enough about helping people. Evil characters want to do whatever they have to in order to get ahead, while chaotic evils just do what they want regardless of who it hurts. The two evil alignments share a distaste for good, but don't generally get along that well.
