Selected Option:


Retrocausality is a tabletop RPG about time travel, in the vein of Bill & Ted's Excellent Adventure or Back to the Future.

Its rules-light, card-based system lets you decide how time travel works. Do you have a specific movie you want to emulate? Do you have Opinions on the Novikov self-consistency principle? Do you prefer not to ask too many questions? Retrocausality can make that happen, and more.

  • Designed to be playable with a deck of playing cards.
  • Convention-friendly character creation: a list of the things you're good at and the type of time travel shenanigans you prefer will do.
  • Rules-light, complex outcomes: Every result is a success or failure, and may also be excellent or bogus, creating a wider variety of outcomes with every challenge. Face cards and Aces have special results on skill checks, to make things more interesting.
  • Time travel rules split actions into their focus (what you're interacting with) and method (the how). Without a specific list of allowed time travel actions, you're free to do what you want!
  • The rules are so light you can use Retrocausality to run a time travel adventure in a different game. That's twice as much game.
  • A guide to support tools that will help make your time travel adventures even better.
  • There's art of a time traveller high-fiving Obama after making Karl Marx a US President. I will not be taking questions.

This 60-page book comes with full-colour art from a bunch of great artists, sample characters, advice on running time travel games, and a tacit admission that I have read Homestuck.

I don't know if it's just the time travel theme, but I feel like I've purchased this before.

Most excellent! But you may want to elaborate a bit more on the rules system and content that we get for these 60 pages.

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.
