West End Games (WEG) was the publisher of Star Wars: The Roleplaying Game between 1987 and 1998, when the company's financial problems forced them to give up the license. Their headquarters was in Honesdale, Pennsylvania.
While all the supplements produced by West End Games are out of print, much of the information included in their sourcebooks,and adventures was used as background material for the Expanded Universe novels and comics, and some of the writers for West End Games supplements went on to write for the Star Wars Roleplaying Game produced by Wizards of the Coast. Much as with Marvel Comics' Star Wars series, relatively obscure characters and settings from WEG supplements are frequently referenced in new Expanded Universe material by such authors as Abel G. Peña and Pablo Hidalgo (himself a former West End Games freelancer). Lucasfilm's current continuity policies have not removed West End Games material from the body of Star Wars canon, except for character and item statistics (which are considered non-canonical game mechanics) and certain background information contradicted by later published stories.
Associated supplements, of varying canonicity, were also published in publications such as Dragon Magazine, Challenge magazine, Polyhedron, and later, Dungeon/Polyhedron. Three West End Games sourcebooks, the Jedi Sourcebook, Tion Hegemony Sourcebook and The X-wing: Rogue Squadron Sourcebook, were cancelled before their release.
