Game System License

A publishing license for third-party products compatible with the fourth edition of a fantasy role-playing game. It grants access to a System Reference Document containing approved trademarks, terms, and short phrases, but no game rules, along with a required compatibility logo. The license may be updated by the rights holder, with changes applying to all licensees, and assigns certain legal costs to licensees in the event of litigation.
