One of the great perks of being a Hero System gamer and member of this forum community, is that we're able to ask rules questions of the guy who wrote the rules, Steven S. Long, and get a prompt reply. In the past Hero Games has compiled these very exhaustive rules questions into a FAQ, viewable on the website as a webpage, and later as a downloadable PDF. Several years ago Hero Games management redesigned the website, and according to Jason Walters, decided at that time not to include the FAQ. But since I still frequently see Hero fans asking rules questions on these forums, there's obviously still a demand for info like this. So I decided to upload my own copies of the rules FAQ. Jason has approved of this.
Here you'll find three separate PDFs, each with rules questions relevant to one edition of the Hero System: the original Fifth Edition (updated until 2004); Fifth Edition, Revised (updated 2005); and also a more abbreviated FAQ for Sixth Edition (as of 2010). I hope you find these helpful.
