Scorn is an amazing, modern horror game about demon hunting and killing monsters in gruesome ways. It's closest cousin would be White Wolf's classic Hunter: The Reckoning, but Scorn is tons gorier, more vulgar, much more blackly funny, and better organized and with far superior art. Scorn also has some of the best original demons I've seen in a modern horror game.
The only, and I mean only reason I didn't give this puppy five solid stars is that most of the spells are inconsistently named. About 75% of the spells in the game have one name in the fiction and another name in the game rule paragraph above the fluff. It's obvious that the spells changed names during the revision process, and an editing pass didn't catch this.
Fix that one problem and you've got a dead solid perfect, rules light action/horror game.
