I really like Cortex’s use of dice from d2 to d12 to set the level of an attribute, trait, or skill. You wind up rolling two or three dice and adding them. If keeps the bell curve of probability that feels natural to me, while causing it to shift for the quality of what’s being rated.

When used in combat, having the number you succeeded by as a base damage, then add a weapon die replaced the old d100/Quality Result rules of James Bond for me, as well. It does the same thing, but without a table. The less I have to reference these days, the better.
