This page collects all the games under an open license like the Open Game License and various Creative Commons Licenses.
Definition: What is an Open License?
This page operates under the following definition:
"An Open License allows the free and perpetual re-use of original material by anybody willing to follow the restrictions of said license, without an explicit contact or negotiation between original author and licensee."
In other words, if something is available under an open license, I can use and re-use it for free, as long as I respect the restrictions laid out in the license, without having to contact the author.
