Someone has a site for this but I can't remember the link. Its a writeup of using the Wound Point/Vitality point system from Star Wars for Dnd 3e. Does anyone have a link to this site?
I wrote the one in Asgard magazine (http://www.d20reviews.com/asgard.htm), which tries to take into account monsters (something that Star Wars didn't do too clearly).
I wrote up a very customisable conversion I call "Severity Points" at my site: Zarrock's Dragonstar - it's in the New Rules section. It is very modular to allow for varying levels of "deadliness". It also includes a pretty easy to use Specific Critical Hit system to tag on.
