From the title page:
The Legendary Games Studio creative staff had a hell of a time coming up with the title of this book… In fact, no less than twenty (twenty !) other titles had been considered before Alf Zyk suggested to call it Unveiled Addenda. Now, for the first time in gaming history, here is the complete list of those twenty titles that almost made it :
Unearthed Miscellanea - Forgotten Arcana - Exhumed Paraphernalia - Rules Supplement n°3
Book of Hidden Lore - Rules & Resources - The M&M Companion - Book of Many Things
Book of Bonus Bonanza - Advanced Addendum - Mythikal Manual - That Damn New Book
Son of Mazes & Minotaurs - Disinterred Marginalia - Excavated Incognita - Odds & Ends
Tome of Lost Knowledge - M&M Adventure Guide - Uncovered Extravaganza - Expanded Minotauria
