The Community Codex Adaptive RolePlay System (known better as CCARPS), is a modular game ruleset. We were deeply unsatisfied by other rulesets and their accompanying license terms, so we set out to create one that we wanted to use.
CCARPS is free to use under the terms of the Creative Commons Attribution-ShareAlike 4.0 International License. The name for attribution is WizardSpire Games.
We are currently working on cleaning up the PDF layout – there are some things that bug us (namely the Disposition section).
If you are interested, please download and the Base Rules and let us know if there is anything you don’t understand!
