* ItsBeenDone: A meta-example. Yahtzee received several E-Mails noting the similarity between this book and a webcomic that [[Webcomic/LookingForGroup also featured an undead mage in a World Of Warcraft-like environment.]] His response to this was that he didn't know of this series while writing it. And besides, the similarities between the two are vague at best (Jim is apathetic; Richard is hilariously malevolent, for example).

The novel receives various {{Call Back}}s in Yahtzee's other books. In ''Literature/{{Jam}},'' one of the programmers who worked on the game treats the hard-drive its stored on as a MacGuffin and threatens to EyeScream anyone who tries to make him leave it behind, and several characters in ''Literature/DifferentlyMorphous'' play [=MOG=]World. The only Yahtzee novelverse that had not acknowledged Mogworld was the Literature/JacquesMcKeown books, which was rectified in the third and final book "Literature/WillLeaveTheGalaxyForGood".
