Yeah, yeah, I'm talking about another Tabletop RPG.
Originally this was the system that was primarily used by Margaret Weiss Productions. As Cortex it was used in things like the Serenity RPG and the Battlestar Galactica RPG. Then as Cortex Plus it was used for things like Marvel Heroic Roleplaying, Smallville, and Firefly.
