Familiar Classes for OSR Games

From publisher blurb: Do you like the awesome class designs of Pahtfinder but want simpler rules? This is the book for you! We tok five classes based on Pathfinder, the Barbarian, Fighter, Ranger, Rogue and Zealot (Cleric). This is the first release in a series. Imagine futuristic Iron Man-style vigilantes, inter-dimensional summoners, rock star bards and more. We also plan to put out further advancement and customization options for the released classes, which will also include equipment lists plus sets of encounter tables designed to give you solo adventures in the vein of Choose Your Own Adventure books or inspiration for GMing your games.
