Plot Unfolding Machine

Suggested Price $3.00

The Plot Unfolding Machine (PUM) is a one-pager GM Emulator that helps you come up with scene proposals, challenges, and stakes for your PCs to fight for. What stands between your characters and their goals? Who is opposing them, and how? What happens next?. These are questions PUM helps you answer, moving your game forward.

By placing conflict at the center of the adventure, you'll find your characters having to fight for their goals, interact with your world building aspects, and have your RPG system to actually matter. PUM's main goal is to bring solo RPG players back to the playing seat, lowering your GM authorship effort when playing.

UPDATE: Plot Unfolding Machine V6 Released!

I've been having so much fun using PUM. In two weeks' time, I'll be writing a 13-week long serialised story for my blog, The Spiral Room. The story is titled "The Chaotician," and the plot will be determined by PUM.
By the way, I've taken to calling the print versions of your book PUMP. "Quick - I need a plot twist! All hands to the PUMP!"

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.
