Hackmaster is perhaps the most well-known RPG first created as a parody in a comic strip. Kenzer & Co gained the right to publish the game as a derivative of D&D after Wizards published Dragon Magazine archives containing KODT strips without seeking proper permission.

This agreement ended two years ago, and Kenzer has now moved forward with a new edition of the game without any protected WotC material, i.e. no longer a D&D derivative. Several source books and extensions are planned. The Basic rulebook is due out next month.
