GNU General Public License

The GNU General Public License is a copyleft license for free software. It is by far the most common license used in games documented by Libregamewiki. Version 3 is the latest and current version.

Although it is intended for source code, it fits other types of works well (and Richard Stallman does not object to such uses ).

Some people prefer GPL (or GFDL) for media over the free Creative Commons licenses like CC BY-SA for compatibility, and because GPL protects the source availability and editability and not just prohibits DRM.

The GNU GPL is by far the most used free software license.
