The Green Hack SRD

The Green Hack SRD


The Green Hack (TGH) is a traditional tabletop roleplaying game, played with paper, pencils and dice. The game's design goal is to be broadly compatible with TSR-editions of the Original Fantasy Roleplaying Game while being as compact, easy to learn, easy to teach, and smooth to play as possible.

This is the Systems Reference Document for The Green Hack system, made available under the Open Game License so that you can use it to make your own games or content. Downloads are available for plaintext (with Markdown formatting) and PDF. A link to a Google Doc you can copy or use to download other formats is also included.

How is this different from The Black Hack?

I love The Black Hack but have found characters to be generally a bit overpowered compared to the level recommendations found in published adventures.  This was in part because I often found myself forgetting to apply things like the Powerful Opponents rule, which I found cumbersome.

The Green Hack replaces the combat system from The Black Hack with one inspired by The White Hack. It's designed for fast and smooth combat while maintaining rough compatibility with old school versions of the original game. IMHO it plays better smoother than The Black Hack with even less need to convert anything from published modules. Meanwhile, combat plays faster than in B/X or other old editions of the Orginal Game. Both PCs and opponents are more likely to hit during combat in The Green Hack, reducing the amount of whiffing but keeping the challenge level consistent with old editions.

What about Macchiato Monsters?

Macchiato Monsters also combines elements of The Black Hack and Whitehack. But Macchiato Monsters mostly leaves The Black Hack combat system intact while importing the magic system from WhitehackThe Green Hack is sort of the opposite: it leaves The Black Hack magic system intact while bringing in a combat system similar to that of Whitehack.

How else does it differ from The Black Hack ver 1?

- Warrior class is pretty different.

- All classes have a few extra features, particularly as they advance.

- Players don't roll to increase stats as they level up.

- Rules for Opposed Rolls, when player characters are in conflict with each other or with noteworthy non-player characters.

- Rules for fighting swarms of opponents.

- Rules for Backgrounds are "Backported" from _The Black Hack_ version 2.

- "Cure Light Wounds" explicitly heals paralysis.

- Probably other stuff I've forgotten about.

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.
