The OGL System is an open roleplaying game system, published by Mongoose Publishing.
It is in fact the d20 System, but it was rewritten in order not to contain any licensed material; for example, the term "d20 System" was systematically replaced by "OGL System".
This system is published in the OGL Rulebooks. It is also described in specific roleplaying games such as in Conan: The Roleplaying Game or Lone Wolf; in these cases, the system was slightly modified to match the universe.
Famous quotes containing the word system:
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
