It's a thrill to see my first commercial release on these virtual shelves!

I'd be glad to hear what you think of it.

Congrats, Jim! As an ERB fan, fellow freelancer, and A.net compatriot, I hope this does well for you.

I am a huge Barsoom fan. I bought it and have looked it over briefly. I will have to do a more detailed reading and do not know where it is going to fit into my current gaming ideas (I have always considered a Barsoomian demi-plane or something). A lot of ideas are going around in my head. I have always wanted to run a game in Barsoom and never taken the time to do all the work. You have done a lot of the work for me. Thanks.

Much appreciated! There's more work to do yet.

Though the rule base is generic, I've aimed to describe the setting as a distinct and unique world first and then to provide sturdy support for cross-setting use. I can easily see these creatures and concepts working as a demi-plane - probably separating out a number of elements related to each other, rather than using the full complexity of the setting.

Gygax included Barsoom in his game. There is a Red Planet in Golarion's system that will no doubt cover some of the same influences. It's nice to see this fantasy subgenre get more exposure.

Two questions, out of curiosity: To what extend did the Mars(es) of Otis Adelbert Kline, Leigh Brackett, Lin Carter, and others play in the creation of this?

Also, is this an officially licensed product with the Edgar Rice Burroughs Estate?

I think it's been a constant influence on many gamers and has seen several published references over the past few years.

This isn't a licenced product though we've been in contact with the Burroughs estate about it. All of our sources are in the public domain.

I'm a fan of Leigh Brackett and also Clark Ashton Smith's Mars stories. I know of O. A. Kline's work and Lin Carter's Mars novels but haven't read them extensively (I see that The Swordsman of Mars is or will be available through Planet Stories, good stuff). This is solely an ERB-based product though, and only, if anything, influenced in tone by any of the other works.

edit: Oh, also, Michael Moorcock, at least the second and third books of his trilogy.

Any thoughts on the included freebie "Combined Creature Creation"? I just put it together for myself to help with monster-building and stat blocks and to list all feats in one place. It's almost pure crunch, mostly tables, from the 3.5, 3.0 and Modern SRD and a couple of third-party sources - whatever I needed to fill in missing or shaky parts of the process - plus a brief step-by-step checklist.
