The lead in blurb here mentions superpowers, but I don’t recall seeing that addressed anywhere in the document. Not even as a “the magic rules also work for supers”, and definitely not a “here’s how you reskin the magic rules for various superhero ideas.”

Two ways to handle this, depending on the hero. Either, as you suggest, reskin magic into powers. The second option is to treat powers as natural weapons, armour and stats, using the small/light 1d6, medium 2d6, big/heavy 3d6 model.

Having 4d6 strength, for example, would not give bigger bonuses, thet are capped at +2, but you would be much more resilient,

Right... but I expected that to be said somewhere in the rulebook, based on that genre having been "promised" here in the product description.

My apologies. It was always the intention that the mechanics be used as a toolkit to build what you wanted, and to power scale that you want. A superpower built on the magic rules could be massively more powerful than one built using the ideas of attacks and weapons. It is in the GM's gift to decide how they would want them implemented.

But, having said that. In the next refresh of the text, I will take your comments on board and I will include explicit advice on psionics and superpowers.

I second this (John R). Explicit rules on psionics and superpowers would make an already versatile system even more fun. I've been looking into how to meld the resources for Traveller (2d6) that do this, and finding the balance is hard. It would be nice having the rules in one place and merged/balanced how the creator intended.

I just bought the Doctor's Without Borders bundle and this file isn't downloading correctly. It keeps giving me a weird text file of mumbo jumbo I don't understand. (php file)

I have removed the watermarking from the file, uploaded a fresh copy and removed the quotes from around the title. I don't know what cause was of the problem but I know of one other person who had this issue a while ago.

Please let me know if it is now working for you.

Worked like a charm! No problems downloading it now! Thanks so much! I'm excited to try this!!!

I purchased the PDF & I'm liking what I'm seeing. Is there any way to get a discount on the softcover book if you purchased the PDF? There quite a bit of typos in the PDF but nothing I couldn't cypher so far. I can't wait to play using these rules & I like the streamlined Mythic engine.

Make sure you are receiving emails from me. A discount is heading your way.

Sorry about the typos. The joy of being a dyslexic writer.

That will be much appreciated. Thank you.

"The player then interprets that answer in would be the most logical (or entertaining) way so that the story can continue. Of course, the answers given by the dice are more suited to stories and gaming rather than the vagaries of the toy. The dice can take the story in new, unexpected, and interesting directions."

This is in the intro portion. Can you clear up "vagaries of the toy"?
Customer avatar
Peter R March 29, 2020 5:30 pm UTC
It refers to the Magic 8 Ball references above that.
Customer avatar
Matthew D April 04, 2020 4:39 pm UTC
Alright. That makes sense.
I found you on the publisher list "PPM" so I think I have that sorted now.
Customer avatar
Peter R April 04, 2020 4:54 pm UTC
I assume you didn't get the discount email then? Could you send me a message via and I will send you a discount code directly. I don't want to bulk send the same message again.
Customer avatar
Matthew D April 04, 2020 6:29 pm UTC
No I didn't. Just me figuring out the site preferences.
Sure can & I just sent the message.

The download for this one constantly gives me a php file. Not sure what is going on, I can download on laptop and rename to pdf but clearly something not working correctly.
Customer avatar
Peter R December 03, 2019 8:15 pm UTC
Have you tried using a different browser to do the download? The pdf is downloading OK for me.
Customer avatar
Jason D December 04, 2019 10:23 pm UTC
Yeah, I did try it on Edge and that worked. On firefox it gives a file called download.php which is the pdf if you rename it. Had the same problem on safari on ipad as I wanted to download it directly to read on there.

Anyway I have a copy now, just obviously something weird going on which I can't work out since it affects multiple browsers I use on several devices.

I am glad that you have the file. I hope you enjoy it.

Rules look good though. Mostly interested for solo aspects since I already do that a fair amount with other rules but this looked a little lighter than some of the stuff I mess with.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
