The Masquerade was the first live-action roleplaying game (LARP) published by White Wolf. Based on Vampire: The Masquerade, The Masquerade was the first game to use the Mind's Eye Theatre (MET) live-action system. The first edition of The Masquerade was originally published as a boxed set, like most other party games that were popular in the 1990s; the second edition of the game was instead published as a single softcover volume, of the same dimensions as most other roleplaying game books. The Masquerade was followed shortly by The Apocalypse, the live-action adaptation of Werewolf: The Apocalypse, and it and the other MET games that followed were only published as single-volume books rather than boxed sets.
