1) I like critical hits.
2) I'm planning on running my next session with variant die rolls for the HERO System. I'm playing with some people with d20 exclusive experience, and I want to make things easy for them. One of the things I'm doing is "higher is better," to keep it in familiar territory.
So, for example, a skill is 10+ instead of 11-. Et cetera.
The math has been coming along nicely, except, in critical hits.
Critical hits require "making a roll by more than 1/2." This doesn't work when small numbers are bad and big numbers are good, and the math doesn't work when the roll is more than double.
3) Any thoughts on how to make critical hits work when the math is "more is better"?
4) For reference, 6E2 118.
