2400: Tempus Diducit


They call it the Unraveling. Or they will, anyway. Hard to say with time travel. Too many trips, and timelines begin to fray at the edges. Most folks just struggle to adapt to this broken world. Some exploit it for their own gain. But for others — the warriors, investigators, and agents of change — there are wrongs to right, paradoxers to catch, and a glimmer of hope of fixing this mess.

Tempus Diducit is a super-slim, self-contained, lo-fi sci-fi RPG about a world where every era is happening right now. It's inspired by every bonkers, kitchen-sink roleplaying game you've ever shaken your head at, and encourages you to bring in characters made from any other 24XX game. It's 3 pages and a cover, fitting on two sides of a letter-sized page, with rules based on the FREE 24XX SRD.

What is 2400? 2400 is lo-fi sci-fi. It’s centuries in the future, and it’s a decades-old modem that screams like a dying robot when it connects to the net. It’s a space ship with an FTL drive, artificial gravity, and a flickering display you gotta tap a few times to see the jump coordinates. It’s hacking something together with whatever cheap materials you have on hand, ignoring the rules until you need them, banging out something that might not sound finished, but definitely sounds fun. It's a series of micro RPGs that might all be in the same setting, unless they aren't.

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.
