This book covers the rules, gameplay, and intricacies of creating and running your own role playing game (rpg) that is player-based, group run, and very much inPerson because you're drawing the maps and running the adventures.
This book uses an example similar game, The Amulets of Aazlim, marking rules and gameplay that has actually worked in real life. This is all intended as a template to help you create your own successful rpg.
