RPG rulebooks work in a similar manner to educational textbooks and players will often find themselves referring to different sections over the course of a game. In the example of something like Dungeons & Dragons, someone who is playing a spellcaster might need to refer to the spells, magic rules, combat rules, and race rules section over the course of a few hours. As such, it's helpful for these books to be well-edited and for helpful page references to be included in relevant sections, so the game doesn't grind to a halt while people are trying to track down a specific rule or table. THEGAMER VIDEO OF THE DAY The World of Darkness game was created by a company called White Wolf. According to the unofficial , the editing job on the early White Wolf books wasn't always up to par, which meant that Vampire: The Masquerade and Werewolf: The Apocalypse books would ask players to find "Page XX". The reason for this error is because writers will often write two Xs in place of an actual page number because the book is still being assembled, so they don't know what exact page they are referring to. The intention was for the editor to replace the Xs with actual page numbers once the book was near-completion. The White Wolf books had a tendency to forget about the Xs and leave them in, which meant that players had no clue what page they needed to find. The biggest offender in this regard was the first edition of Werewolf: The Apocalypse, which featured several "Page XX" gaffes. As such, White Wolf decided to reference the mistake by including an actual "Page XX" in the first Malkavian clanbook, which meant that one technically existed. The leather-bound version of Vampire: The Masquerade 20th Anniversary Edition also features an XX on the spine, which is both a reference to the Roman numeral for twenty and to Page XX. The production values of the new Vampire: The Masquerade books are far higher than the ones from the early White Wolf days (depending on how much you prefer photos over artwork,) so the common errors of the old days are gone. Page XX now only exists as an in-joke for the fans of the early White Wolf books, who remember the days when they had to make their own page references. Source:
