Swords & Wizardry 4th printing is now available. Go get it immediately. It is still my favorite retro-clone.
I've only skimmed through it, but I can already tell I like the layout better than the Complete Edition, and it is back to the original, and more appropriate, cover. That cover was very well done it just didn't feel right for S&W, unless it was for a Cthulhu edition of S&W! Still, I can't help but feel the 1st printing nailed it so well that it is difficult to improve upon.
Though I nit pick (can't help it) S&W IV looks potentially good.
