S.I.T.R.E.P is a
approach to roleplaying games.
What is S.I.T.R.E.P?

A lightweight, accessible RPG system intended for groups with less time for heavier systems, for those GMs looking for a streamlined but mechanically-rich RPG system to use for their next game, or for introducing new players to roleplaying games without dropping them in the deep end.

How does the system work?

This system is d10-based and uses a single d10 for resolving everything. It uses simple math that doesn't require massive lookup tables or deep knowledge of obscure mechanics to build a functional character. Chargen is straight-forward -- fully completable in less than five mins.

How is the game designed?

It is a component-based system and aims to be loosely coupled, encouraging customization by gamemasters without worrying about breaking the rest of the system. Gameplay mechanics are implemented within an inheritance structure with the aim of avoiding exception-based ruling as much as possible -- mechanics applied one way are used similarly elsewhere. The system is designed with a mechanics-first ethos, aiming for great gameplay regardless of the setting.

Can I use my own homebrew with it?

Can be used with your own homebrew settings along with official Black Lion Games published settings (our first one to be published in the near-future!). The book is compact: 50+ pages of pure content. It is focused solely on gameplay mechanics and rules so you can easily layer your setting on top of it.

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.
