If you read all four parts of Core UF...plus most of the UF omake...plus Hopelessly Lost...plus random parts of NXE (unMSTed and what has been riffed)...plus that Aa! Megami-sama fic...plus the UF ripoff as written by a hopeless Gryphon/Eyrie fanboy...plus the MSTing of SF:WL...
...er, anyway, you begin to get most of the in-jokes. ^_^;;
(Random Note: I want someone to riff the last chapter or so of NXE. Just because of what Gryphon turned DJ into...)
