I've kind of fallen in love with LotFP. It's not so much the rules, though I'm certainly not complaining about them. It's the vision of a twisted journey into a history where witchcraft is real, and demons might eat your soul. There's really nothing quite like it.
Having said that, it's definately not for everyone. If you have a particularly weak stomach, it's not for you, and I wouldn't reccomend trying a game with any group who aren't fully comfortable with each other, as the modules can go in some pretty dark places. But I feel very happy that this product exists, and it's definately my favorite old-school RPG.
