Definetly the most ingenious and well thought out hell campaign I have come across. The aventures are details and mostly ready to use. I got lost a few times in the mire of lore and options, but they always gave me great ideas to run with. I would have bought this for the local descriptions and monsters alone. Even if you don't like hell campains, simply flavour them differently and you have a hiest with thrills on every corner.
