The EN World kitten
Fun fact: I downloaded the printer-friendly versions (except for the very last one, which would only load the original HMTL version for some reason) of all one hundred fifteen articles of Gary Sarli's "Jedi Counseling" series from WotC's website – where he answered questions and issued errata for Star Wars d20, Star Wars d20 Revised, Star Wars Saga Edition, and the Star Wars Miniatures game – and combined them into a single PDF.Never said I did. Dont want such a book. I'm saying there was enough errata generated for 4e to fill a literal book.
The entire file is 443 pages in length.
EDIT: Whoops, looks like Gary Sarli only took over the column as of the fifty-first installment; prior to that it was handled by JD Wiker. My mistake!
