The Marvel Heroic Roleplaying Game’s Civil War Event Book is hard to quickly summarize as anything but massive. From its massive ambitions, to its incredible scope and to the sizable amount of content, the book is in all aspects a massive value. It might seem like an equally massive undertaking for the prospective RPG gamer, but the guidelines help somewhat in keeping you up to speed. You don’t have to be a comic book expert in order to run it. However, I would still recommend some familiarity with the Civil War.
