Lamentations of the Flame Princess

Lamentations of the Flame Princess, subtitled Weird Fantasy Role-Playing, is a dark fantasy RPG in the "old-school" vein. That means that it shares many characteristics with the first edition of Dungeons & Dragons.

It is a class and level based system with races modeled as character classes. A character's attributes are determined randomly. They give modifiers to various other stats and actions (hit point bonus, damage bonus, armor class bonus, etc.). Hit points of a character are also rolled up and depend on his class and level. Every character has also five different saving throws against various hazards (magic, poison, area effects, etc.). The last important characteristics are the attack bonus and the armor class.

Attacks in combat are rolled on a d20. The character adds his attack bonus and needs to score higher than his opponent's armor class. A successful hit deals damage equal to the weapons damage rating which is subtracted from the opponents hit points. The game allows for some variant tactics like defensive fighting, parrying, aiming, mounted combat, etc.
