After just having seen this movie, it screams in my head to be converted to unisystem. The first book that came to mind? Army of Darkness, if for no other reason than the mass combat rules. I suppose if you mix it with Terra Primate and All Tomorrow's Zombies, I'm sure it would mesh into the system really well. Thoughts or ideas?
And for those of you who have not seen it yet...go see it. Right now. Why are you still reading this? You should already be in the car, on the way to the theater. Yeah, it's like that. Avatar is MADE OF EPIC.
