I've been playing a bit of Lamentations of the Flame Princess [Grindhouse Edition] these last two weeks, and I have to say, I'm impressed: the game is intuitive, easy to use, retains basically all what makes D&D, D&D...in fact, I'll go out on a limb and say it's what D&D 4th edition always should have been and what D&D 5th edition should be. (If I have a complaint, it's that the art feels like it's trying too hard to be shocking in places, though if that's your only complaint about a game...)
But that's not even the best thing about it. No, the best thing about it is that the rulebooks are in fucking A5. If there ever was a way in which God intended rulebooks to be set out, it would be A5 format paperback. Easy to flick through, light, will fit in a man-bag or brief case, and way more readable in bed or on a train than clunky A4 hardbacks. For that alone, James Edward Raggi IV, I salute you.
