The Old School Renaissance Handbook

From publisher blurb: You may have heard of the Old School Renaissance, an enthusiastic movement that champions old-school gaming and old-school systems. Here's the problem: there are dozens of old school rule sets. So which one should you try? The Old School Renaissance Handbook profiles 28 popular old-school systems, including their basic mechanics, character attributes, and advice for DMs and players. There's even a handy one-page table comparing all these systems on price and complexity. Plus, the book stats out the same five first-level characters in all 28 systems. Compare systems easily, and quickly jump into a game with these pregens. The Handbook also includes interviews with Kirin Robinson of Old School Hack, James Raggi III of Lamentations of the Flame Princess, Jason Morningstar of Dungeon Squad!, Larry Moore of BareBones, Michael Wolf of Warrior, Rogue & Mage, and Sage LaTorra and Adam Koebel of Dungeon World.
