The CORE system is built for shared creation of exciting sessions, and easily skinned for any setting.

Minimal Rules.
Maximal Possibility.

CORE produces emergent stories that are character-driven, dynamic, and unpredictable,
with few rules to learn. The design focus on simplicity, speed, and improvisation.
The CORE MICRO rules are built for easy skinning, allowing you to take your concept,
or an existing fictional world, and bring it to the table quickly for collaborative play.

• The system uses pools of d6s, with a single mechanic
• Choose your Character Generation system: Point-buy, Templates, or Rolled
• LifeShapers provide background stories & motivations for player characters
• Progressive Character Generation produces characters who change as they develop
• Skills, Gear & Actions are narratively interpreted, producing unique details.
• Action Resolution is shared & interpretive, with a range of dramatic outcomes for every roll
• Skin the system to bring your world to life, quickly and easily

CORE Micro was designed by Tod Foley, author of DayTrippers, Other Borders, and CyberSpace.

"The system is narration-based with mechanics that practically melt away."
- Jesse Pyne, Monster Hunt Cast

"A flexible system. It balances story and rules, and it's easy to pick up and play."
- Shawn Koch, author 'Liquid Hitler'

"Core is a fun, minimalist rules set that doesn't get in the way of good story telling."
- John Haremza, Legends of Tabletop

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.
