Skrapwelder used modified Valor Steel and Flesh rules plus a witches brew of encounter charts and zombie generators. His Hat, got a rating of "Nice HAT!" from a few, though he misplaced the 9 of spades card in the hat band for awhile...

. On the defiently good side, everytime your character or flunkys killed a zombie etc, you got a candy treat from the jack-o-lantern beside his initative deck.
Funny you should mention LARPing, there is a LARP group that does the Masquarde? (spelling..) dark vampires and all that at the game shop at the same time we were playing.
