What if 1st Edition AD&D had made it explicit that Alignment referred to what side your character was on in the eternal war between the various Outer Planes? Rather than write something like "Lawful Good" or "Lawful Evil" under Alignment, you would have written "Seven Heavens" or "Nine Hells". Perhaps your character didn't care or was opposed to the war itself, in which case they would be "Neutral". Alignment would never have become a description of personality, but been clearly a designation of what cosmic army your character was allied with. How would that have changed the game? Would it have been beneficial or detrimental?
