AWESOME! I have the pack, but have yet to play them. I'm typically NOT an alternative life-state player, so I've never really delved into any of the gameplay for them.
But, the story that's been brewing in my head for the last week incoporates a litte bit of some occult gameplay (the 3 major ones, that is). So I was going to be asking these same type of questions soon.
Right now I'm only at the point of jotting down some initial backstory ideas for my characters, but this answers a lot the questions I had too and helps so much because I also was wondering if you could prevent rampaging when the story needed.
