Valiant Universe RPG Comic Book Play GuideThe Valiant Universe RPG Comic Book Play Guide is an illustrated introduction to roleplaying. Though superhero-focused and written around the Valiant RPG from Catalyst Game Labs, it’s not a tutorial for those specific rules. Rather it’s a guide to the concept or activity of roleplaying—and in a form meant to be the least intimidating as possible.

Even better, it can be downloaded for free [PDF].
