Which License Applies to Which System?
TheCrazyGM hosts content across multiple tabletop roleplaying game systems. Because licensing in tabletop publishing is per-system and per-book—never a blanket sitewide license—each game system operates under its own specific open license regime.
1. Licensing is Per System and Per Book
A game system never claims a license regime for publications outside it. Content from one book does not dictate the terms of another, and no system applies a blanket license to unrelated works.
2. Regimes Are Kept Distinct
The Open Game License (OGL 1.0a), Creative Commons (CC-BY-4.0), and the Open RPG Creative License (ORC) are separate legal instruments. Each has its own rules for notices, attribution, and grant boundaries.
3. No Unreviewed Mixing
Mechanics from different license regimes cannot be combined into a single derived record. Each library record is grounded strictly in the regime permitted for its source material.
| System | Slug | Family | Allowed Regime | Regime Hub | What the Library Displays | Authoring / Forge |
|---|---|---|---|---|---|---|
| Pathfinder 1st Edition | pf1e |
d20-3x |
OGL-1.0a (Open Game License 1.0a) | OGL 1.0a Hub |
Verbatim Section 15 copyright notice chain for each cited sourcebook, Section 15 register anchors (#src-<slug>), and explicit separation between Open Game Content and Product Identity.

pf1e)
The Pathfinder 1e compendium is published under the Open Game License Version 1.0a. In our code ceiling and database registry, its allowed regime is strictly locked to ogl_10a.
- Source Attribution: Every record links to its source book's Section 15 entry in the site's public register.
- Content Boundaries: Game rules mechanics are treated as Open Game Content. Trademarks, setting lore, character names, and logos remain reserved Product Identity.
- Authoring: Community and publisher contributions are supported through the Forge with signed attestation.
dnd5e)
The D&D 5e compendium is published under Creative Commons Attribution 4.0 International (CC-BY-4.0), drawing from Wizards of the Coast's System Reference Documents. Its allowed regime is strictly locked to cc_by_40.
- Source Attribution: Every entry carries the required verbatim attribution statement prescribed by Wizards of the Coast for the cited SRD edition.
- No OGL Assumptions: 5e compendium entries do not carry Section 15 notices or OGL declarations.
- Library-Only: To ensure strict compliance with CC BY 4.0 attribution terms, community contributions are currently disabled for 5e.
The Open RPG Creative (ORC) License
The ORC License is an open license designed specifically for tabletop roleplaying game mechanics. It has one immutable text and no version number (filed under Library of Congress registration TX 9-307-067).
When a future system utilizing the ORC License (such as the Pathfinder 2nd Edition Remaster) is chartered on TheCrazyGM:
- It will launch under its own cleared regime (
orc) with its own dedicated hub at/legal/orc/. - It will not commingle pre-Remaster OGL material with ORC material within a single derived record (following Paizo's explicit guidance that OGL and ORC content cannot be converted into each other).
- It will be added as a distinct row in this registry table, checked automatically against our code ceiling.
