I'm currently about 40% finished with a novel entitled Bel Canto and in the first chapter I make a joking reference to the Dungeons and Dragons games and Final Fantasy games calling them Dungeon Dragoons and Never-Ending Fantasy 49. I don't think that making those references is illegal, but I thought I would check to see if anyone here knew for certain whether or not I would be allowed by law to include those references. Does anyone know?
