Free RPG Day attempts to replicate the success of Free Comic Book Day by teaming up different publishers to release free games, supplements and other gaming goodies once a year. The inaugural event was held June 23, 2007 and featured Troll Lord Games, Chessex, Goodman Games, White Wolf, Mongoose Publishing and Skirmisher Publishing, with others expected to join. In 2008, it will be held Saturday, June 21.
