Palladium actually ripped that idea (the victims game and much of Beyond the Supernatural) from Call of Cthulhu by Chaosium Games (sp?).
Palladium is well known to me to have lifted a great many of thier idea from elsewhere, this news is no suprise to me, though I was not aware.
I've given Cloverfield a pass. Neither I nor my stomach are fans of Vomit-Cam filming techniques; had enough of that with The Blair Witch Project.
I can't comment as I saw Blair Witch on DVD only and I saw Cloverfield at a Cinema Pub; smaller screen, house lights not fully off, flat seating, eating food and drinking during the show.
