On 16 March 2000, LucasArts Entertainment announced a partnership with Verant Interactive Inc. and Sony Online Entertainment to create the first massively multiplayer Star Wars online role-playing game.[1][2] The then unnamed game would be developed by Verant with online play supported by SOE. This was the same team responsible for creating and supporting the popular EverQuest multiplayer online game. LucasArts would be responsible for all distribution of the Star Wars online game. The announcement included an expected release date some time in 2001 and that the game would take place during the original trilogy era.

LucasArts officially announced the brand name of the game to be SWG Credits on 29 November 2000.[3] The announcement claimed the first round of testing for SWG Credits was expected to start in late 2001 which would push back the official release date to an unknown time. The game's official information site was launched on 30 November 2000 in conjunction with SOE and featured frequently asked questions about the game and message boards fielded by members of the development team.[4]

We see this Web site as an important step toward building a strong community for the SWG Credits line of games. We firmly believe that consistent and open communication with fans will be one of the keys to the success of the Star Wars Galaxies Credits experience.
—Simon Jeffery, president of LucasArts[3]
On 17 May 2001, even before the game went into public beta testing, the first expansion's development was announced.[5] The yet unnamed add-on, which was expected to be available six months after the initial product release, would be a space simulation and enable players to own and fly starships which would allow interplanetary travel and space combat. The release date of the initial product, the ground-based component, was updated to the second half of 2002. The staggered release schedule of the space component of the Star Wars Galaxies Credits series was said to benefit players because they would have time to establish their characters and explore different elements of the core game before adding the space layer.[6] Traveling between planets would be accomplished through the use of public shuttles, which would ferry characters from world to world.

A new official site was also released on the same day that put more of an emphasis behind the community of the game. It included new screen shots, movies, an updated FAQ, concept art, development team member's profiles, features about the game, and a new forum.[7] The site reached 100,001 users by December 2001.[8] Throughout the next year after the release of the new site, new content would be revealed. This content included information on species and locations, new images and movies of different game elements, and 360 degree QuickTime VR panoramas of different locations.

Verant began accepting applications from users in May 2002 who were interested in participating in a closed beta test for SWG. The closed beta test would begin in July 2002.[9] SOE would share more information on the game as the beta moved forward. This would include more screen shots, information on match making services, the fact that players would be permitted only one character per server,[10] and skill trees and how the skill-based system would function.[11] LucasArts also announced on 20 May 2002 that both the Xbox[12] and PlayStation 2[13] would get a version of the game, but these would later be cancelled.

LucasArts officially confirmed a release date of 15 April 2003.[14][15] They also announced on 20 December 2002 that the ground-based component of SWG Credits would be called An Empire Divided and that the game's online community had grown to over 400,000 users since its inception in November 2000. At the time, this represented one of the largest ever fan communities amassed for any game prior to retail availability.[14]

An Empire Divided would later be delayed to an unknown time,[16] but on 17 June 2003, LucasArts confirmed SWG Credits: An Empire Divided would be released on 26 June 2003.[17]

In 27 August 2008, after the success of SOE's "Legends of Norrath", LucasArts and SOE released "Champions of the Force" (see below), an online trading card game based on SWG Credits.

Star Wars Galaxies Credits has gone through 2 major "upgrades": the Combat Upgrade (CU) and later the New Game Enhancement (NGE), its current form.

On 16 September 2009, SOE informed all current and past account holders of the forthcoming closure of twelve servers (galaxies) 'due to the recent popularity of the Free Character Transfer Service'; the servers intended on being withdrawn were listed as:- Corbantis; Europe-Infinity; Intrepid; Kauri; Kettemoor; Lowca; Naritus; Scylla; Tarquinas; Tempest; Valcyn; Wanderhome. Character creation on these servers was disabled on 15 September 2009 with the final closure of the servers on October 15, 2009. Players with characters on the affected servers were also offered free character transfer to one of the thirteen remaining servers.
