Question: The convention where Star Wars: X-Wing Miniatures Game was released had how many unique attendees in 2015?

Star Wars Battle Pod is a 2014 arcade game based on the franchise "Star Wars".  It was unveiled at the New York Comic-Con on October 8, 2014.  The game consists of multiple scenarios that correspond with one of the major battles in the original trilogy.  There are five scenarios, the Battle of Yavin (Yavin) from "Star Wars" where the player is placed in an X-wing attacking the Death Star to prevent it from destroying Yavin 4, the Battle of Hoth (Hoth), from "The Empire Strikes Back", where one pilots a snowspeeder to assist in the evacuation of Hoth from invading Imperial forces, a speeder run through Endor (Endor) where one helps Han Solo make it to the shield generator to destroy the Death Star's shield for the rebels in space.  and the Battle of Endor (Death Star II) from "Return of the Jedi", which places the player in the cockpit of the "Millennium Falcon" to try to destroy the Death Star II and end the war.  There is one scenario that doesn't follow the storyline of the movies but sets its own path, (Vader's Revenge).  This scenario takes place literally seconds after the destruction of the first Death Star where one plays as Darth Vader who is trying to prevent the rebels from escaping with a piece of the Death Star with the ability to eliminate Han Solo in the process.  Another version of the game adds a scene from "The Force Awakens", where the player pilots a T-60 X-Wing to engage First Order ships on Takodana and protect General Leia's transport. <SEP>  It features traditional pen-and-paper, board, and card games, including role-playing games, miniatures wargames, live action role-playing games, collectible card games, and strategy games.
