For the second edition of the Legend of the Five Rings (L5R) rpg, they split the core rules into two books: a Player's Guide and a Gamemaster's Guide.
Notably, the game is listed as a Wizards of the Coast endorsed product as this arrived during the period when the L5R CCG intellectual property was under WoTC's control. It advances the metaplot to post-Clan War and closer to the first CCG material. It integrates a great deal of material from various supplements for the first edition of the L5R rpg.
