Alignment-free D&D?

[CarpeGuitarrem]

One of the ways I've seen alignment-free D&D done is that only creatures of extremes show up as good/evil/chaotic/lawful. Thus, the average guy in the street doesn't show any alignment but a paladin or a fiend would show up as good or evil, respectively.

I like that. So you have to do something to deserve your alignment. A Good character works hard to keep up that alignment, and an Evil character does heinous things to earn that alignment.
