Yes, I have debated whether or not to use Ye Auld's Lawful-Neutral-Chaotic alignment system before. I more-or-less dismissed it here and brought it back here, both over a year ago. Sigh. But I'm back with renewed vigour on the project and I find myself going back to my original rejection of Alignment as-is. I'd stress that this is purely in regards to Under the Dying Sun and not Ye Auld Game in general; as I posted before, the triune alignment system works very well for most of the straight-up fantasy settings I can imagine. But, as I said in the first post on the subject:
...grand cosmic conceptions of Chaos and Order seem a bit alien to my vision of Athas [obviously not Athas anymore]. This is an intellectually impoverished world where people are mostly just trying to not die from dehydration, falling into silt lakes, or being eaten by Halflings...er...Wild Men.
And mechanically, it seems useless as there is no Protection from Evil Discipline or alignment-bearing magic swords.
I find myself going back to the idea of what might be called "Basic Instinct" (although I'm of an age where I don't think I could actually use that name without making a beaver joke). The idea was for the player to define one elemental urge around which the character operates: Food, Love, Sex, Power, Knowledge, Freedom, and so on. It won't have any mechanical meaning, but it would serve as a kind of one word resume of back-story and motivation and all those other role-playing concepts that are cool and all, but which take up a lot of time to create and which seem to have really been a waste of time when you die five minutes into the game, having been eaten by an ill-tempered weed or a crafty, psychic octopus.
Still, even a one-word thing might be more work than you want to demand from a player. Maybe the concept isn't worth keeping at all. I'm struggling on this one.
