Vampire: The Masquerade 20th Anniversary
From VTR
Published in 2011, this book collated much of the Vampire: The Masquerade Revised edition materials including: bloodlines, new disciplines, and merits and flaws that did not exist in the core book. It also further revised the rules in accordance with what players suggested was appropriate.
For the purposes of this game, these rules are what we are using by default as they are much better balanced than even the revised rules. There are some exceptions, especially with regard to character creation (See: CharGen)
