Star Wars: The Old Republic is a Star Wars MMORPG developed by BioWare set three centuries after their Knights of the Old Republic RPGs and approximately 3600 years before the feature films. Centuries after the events of Knights of the Old Republic II: The Sith Lords, the Sith Empire have returned to the galaxy to attack the Republic and its Jedi protectors to avenge the Sith's defeat in the Great Hyperspace War over 1,300 years previously. A tenuous truce was established after decades of war but the peace is fragile, and it is only a matter of time before the two factions break out into warfare.
The game's most unique aspect is its presentation; unlike many MMOs, the game is very focused on story, featuring fully voice-acted cutscenes for almost every quest, as well as lots of player decisions, similar to the Mass Effect series. It was released on December 20, 2011 (December 22 for some of Europe).
When George Lucas sold Star Wars to Disney, due to the logistical issues of being an MMORPG running both before and after Disney's Continuity Reboot of the franchise, the game has existed in a weird canon limbo, protected under a Grandfather Clause as the final sanctioned source of story content for Star Wars Legends as of 2021 (in the form of DLC expansions) as opposed to the rebooted continuity made up of works made from 2014 onward. In the meantime, Lucasfilm has opted to not tell canon stories in this particular era until BioWare has completed this game's story, instead reintroducing bits of lore tied to the game and its two predecessors in stories set thousands of years later in canon equivalent of the Legends timeline. Meanwhile, the line of The High Republic works similarly explores what he Jedi were like before the Fall of the Republic, but the narrative takes place much closer to the events of The Skywalker Saga.
A series of three books serve as a prelude. Fatal Alliance (dealing with tensions in the truce), Deceived (Malgus's story), and Revan (detailing just what happened to Revan and the Exile after the events of Knights of the Old Republic). Another novel, Annihilation, takes place circa the time of the game and focuses upon Satele Shan's son.
The game has received several full expansions, which extend the story and gameplay beyond the initial class quests:
- Rise of the Hutt Cartel was released on April 14, 2013 and deals with the eponymous Hutt Cartel's incursion on the planet Makeb and raises the level cap to 55.
- Galactic Starfighter was released on February 4, 2014, emphasizing introducing space combat to the game as opposed to adding new story content.
- Galactic Strongholds was released on October 14, 2014, and also does not feature story content like its immediate predecessor, though it does introduce player housing and flagships for guilds, alongside access to the Sky Palace on Nar Shaddaa.
- Shadow of Revan was released on December 9, 2014, and deals with Darth Revan's return while introducing the planets Rishi and Yavin 4, raising the level cap to 60.

Set five years after the current timeline, the players are released from carbonite freezing to find both the Republic and Empire conquered by the Eternal Empire, which, as the Outlander, they must stop. The storyline was given an initial release of nine chapters. Additional chapters were released about once a month starting in February 2016, completing in August 2016.
