I figure we could use a palate cleanser. So, how about alignment? Do you prefer the classic nine, the 4e five, or something else? What about Chaotic Neutral – 1e/2e's random wackiness or 3e/5e's anarchist?
The oWoD system of nature/demeanor. You get a long list of personality archetypes. Pick one as how you mostly present yourself. The other is your true nature, which is probably at least slightly different. You regain resources from acting in accordance with your nature. (Inspiration would be the way to do this with 5E.)
Cosmic Law, Chaos, Good, Evil and those weird Neutral dorks should be factions one can align with.
Don't use it. Haven't for decades. Makes no significant difference in the game as far as I can tell. You have to tweak a few spells and items.
And it makes character creation really weird. I can't imagine asking my creative writing students to start by "imagining whether this character is lawful evil or chaotic good."
