So late on Friday, January 29, 2021 I received an email from Lulu.com informing me my account had been deleted because Expanded Petty Gods contained material that was in violation of someone else's copyright. Of course, this came too late for me to contact anyone before the weekend (as if I have ever in the last 12 years been able to contact anyone directly from Lulu.com). And, of course, they did not include the complaint itself, so I have no idea what the claim is in regards to. After all, Expanded Petty Gods is a massive thing (even by old-school gaming standards), and it could seriously be anything (so much art, so many entities that could raise IP issues, etc.). I honestly and truthfully did my best to vet all the content, and tried to err on the side of caution in every instance where it was even questionable.
Most of you have seen the book, so you understand what a daunting task this was.
Restarting at Lulu.com for other titles will be a PitA, but not a major setback. Losing my DriveThruRPG status, on the other hand would be akin to taking a critical hit from 10d10 fireball and failing my saving throw. So, in order to preemptively protect my DriveThruRPG account from similar censure (please understand, I have had no complaints there), I've retracted Expanded Petty Gods from the site, and deleted the related files). It will no longer be available from DriveThruRPG.
For now, consider Expanded Petty Gods in print a collector's item, and the PDF version something relegated to the "sharing community."
BTW, I do have one copy of EPG left in my cache, if anybody wants to trade it for a copy of Deities & Demigods that includes the Cthulhu Mythos.
