In 1992 West End Games published the second edition of the game, in which the title remained unchanged. Even after Disney's reboot of the Star Wars Expanded Universe in 2014, much of this nomenclature still exists in new canon works. Many of the first uses of Star Wars alien names (such as the Twi'lek, Rodian, and Quarren) appeared for the first time in WEG's Star Wars books. Lucasfilm considered the West End Games' Star Wars sourcebooks so authoritative that when Timothy Zahn was hired to write what became the Thrawn trilogy, he was sent a box of West End Games Star Wars books and directed to base his novel on the background material presented within. The game, based on WEG's earlier Ghostbusters RPG, established much of the groundwork of what later became the Star Wars expanded universe, and its sourcebooks are still frequently cited by Star Wars fans as reference material.
