Query: Strange, somewhat useful, but a Gygaxian ego trip, IMHO.

Parts of the book are useful, but I really found nothing useful. At times, it struck me as though I was being talked down to, by someone who obviously considered himself far superior to me. I also take issue with the fact that Gygax takes most of the credit for creating D&D, giving Dave Arneson very little credit for his efforts, and his original D&D campaign, Blackmoor, which is still running today, using Arneson's original rules!If you can locate a library copy, read it, and judge for yourself. I would not recommend purchasing a copy simply because it fails to deliver on what the title promises.
