A Weird Fantasy Role-Playing game, by James Edward Raggi IV.
(Text from LotfP.com [warning: gore])
"LotFP is a tabletop role-playing game born out of the mechanics of old school fantasy gaming and the love of underground heavy metal, horror literature and film, and in fact all things strange and macabre. From inspirations as diverse as Lovecraft and Troma, Argento and Barker, the NWOBHM and the Stockholm death metal scene, Vance and Morrison, LotFP's cadre of writers and artists deliver mind-bending and merciless content for your game table. Rules-wise, LotFP belongs to the "Old School Renaissance" family of games that uses the Open Game License to recreate game rules of the late 70s/early 80s, with LotFP's particular twisting of those rules flattening out the power level a bit and emphasizing a more horrific and go-for-the-throat attitude."
"The rules themselves are mostly familiar and normal. You don't read the rulebook and think, "Oh, that's strange!" Well, maybe in a few places. Anything in the actual rulebook becomes in effect normal and not weird while playing the game. The idea is that the characters are normal (for values of "normal" that may or may not be present in a fantasy RPG setting), and it's what they encounter during play that is unusual and strange and where the weird is found. So in practical terms, the weirdness lies in the adventures and support material, and consists of challenges to both the characters' and players' perception of what is supposed to be happening in the game. You'll just have to deal with the fact that the rulebook is "only" a solid interpretation of classic RPG rules, with application left up to your own imagination."

"Beyond the veil of reality, beyond the infl�uence of manipulating politicians, greedy merchants, iron-handed clergy, and the broken masses that toil for their benefi�t, echoes of other realms call to those bold enough, and desperate enough, to escape the oppression of mundane life. Treasure and glory await those courageous enough to wrest it from the darkness. But the danger is great, for lurking in the forgott�en shadows are forces far stranger and more perilous than even civilization. Th�e price of freedom might be paid in souls.
LotFP: Weird Fantasy Role-Playing presents a sinister and horri�fic twist on traditional fantasy gaming. Simple enough for a beginner yet meaty enough for the veteran, this game will make all your worst nightmares come true."
