LEGO Star Wars: The Complete Saga is a video game drawing its inspiration from the LEGO Star Wars toy series created by The LEGO Group. It merges the widely acclaimed LEGO Star Wars: The Video Game with its follow-up, LEGO Star Wars II: The Original Trilogy. This title became available on November 6, 2007 for platforms including the Xbox 360, PlayStation 3, Wii, and Nintendo DS. Subsequently, a PC edition was launched on October 13, 2009. The Mac version, brought to players by Feral Interactive, debuted on November 12, 2010. Progressing forward to November 12, 2013, LEGO Star Wars: The Complete Saga gained the capability to be played on the Xbox One via backwards compatibility from the Xbox 360. The iPhone version, published by Disney Interactive, was then released on December 12, 2013. Later, on February 19, 2016, Warner Bros. Interactive Entertainment released the game for Android devices via Google Play. Furthermore, the DS iteration is playable on the Nintendo 3DS due to its backwards compatibility feature.
LEGO Star Wars: The Complete Saga presents a lighthearted interpretation of the prequel trilogy and original trilogy films. Traveller's Tales, who also developed the other titles in the series, created this game. LucasArts acted as the publisher, a role they also held for LEGO Star Wars II: The Original Trilogy. This version incorporates the levels and characters from the initial two games, alongside supplementary content for the levels. Players can access a roster of 128 characters, in addition to expanded and new levels. Rather than a complex narrative, the game offers a humorous summary, emphasizing key moments. For example, Luke Skywalker's acquisition of his father's lightsaber from Obi-Wan Kenobi results in the accidental decapitation of C-3PO. The characters communicate through grunts and vocalizations instead of speech. This is sometimes played for comedic effect, such as when Darth Vader reveals his identity to his son by holding up a picture of himself with Padmé from Episode III, and Princess Leia's plea to Moff Tarkin to spare Alderaan is reduced to hand-waving and "blah blah blah" vocalizations.
The levels initially featured in LEGO Star Wars: The Video Game now include elements akin to LEGO Star Wars II: The Original Trilogy, like Power Bricks and vehicles. New features encompass enhanced Force abilities, fresh power-ups, and a Challenge Mode. The speeder chase level, previously cut from the first game, is now playable, as is Zam Wesell. The gameplay largely involves collecting "studs," small LEGO pieces that function as the in-game currency.
Moreover, the Playstation 3 and Xbox 360 editions feature online co-operative gameplay, enabling two players on different consoles to collaborate; single-console co-operative play is also available. The Playstation 3 version also supports 1080i resolution output. Conversely, the Wii version forgoes online play and High Definition video, instead utilizing the console's motion-sensing capabilities for driving vehicles and attacking. For instance, a Jedi attack involves swinging the Wii Remote in a manner mirroring the character's in-game movements.
Graphically, the Wii version mirrors the appearance of the original game and its sequel on the Playstation 2 and Xbox. However, the Playstation 3 and Xbox 360 versions boast graphical enhancements, including depth of field, blooming, bump mapping, higher texture resolution, and more detailed character models. For instance, the minifigures' legs were square in the initial two games, but "The Complete Saga" features fully modeled interiors. Despite these upgrades, the number of objects on screen remains unchanged. The Battle of the Grassy Plains scene, for example, lacks numerous objects.
In the original LEGO Star Wars: The Video Game, the Episode III levels utilized music from other episodes due to the unavailability of the Episode III soundtrack. The Complete Saga rectifies this, incorporating the correct music throughout the game. However, this correction applies only to in-game music; the cutscene music remains unchanged. For example, Obi-Wan's arrival on Utapau to confront General Grievous uses music from the Battle of Endor, and the twins' birth is accompanied by the concert piece Luke and Leia from Return of the Jedi.

This game includes 36 levels, many mirroring those in the original games. A level centered on the pursuit of bounty hunter Zam Wesell, initially a deleted level from LEGO Star Wars: The Video Game, has been incorporated, alongside a Secret Level depicting Anakin Skywalker's destruction of the Droid Control Ship (though still not part of the Episode I level set). The game's narrative spans from "the Trade Federation's 'negotiations' with Obi-Wan Kenobi and Qui-Gon Jinn in Star Wars: Episode I The Phantom Menace" to "the space battle above Endor in Return of the Jedi," focusing solely on events depicted in the films (excluding the Clone Wars franchise, though The Clone Wars was covered in LEGO Star Wars III: The Clone Wars).
The "Gunship Cavalry" level was redesigned to emulate the open vehicle gameplay of LEGO Star Wars II, while "Mos Espa Podrace" was consolidated into a single, extended track, diverging from the segmented design of the original game (which remains playable as a Bonus Level). These Bonus levels and 10 additional Bounty Hunter Missions introduce new challenges to the Prequel Trilogy. Furthermore, the Episode I-III levels have been modified, requiring characters to construct, operate vehicles, wear helmets, and access bounty hunter areas. Some secrets from the Prequel Trilogy have been altered, necessitating prior experience with the Original Trilogy to access them. An example is a Stormtrooper Door in Ruin of the Jedi, found in the Episode III Level set, and in the fifth Chapter of Episode I, where the player can use a small vehicle to help make the journey across the Theed Hangar shorter.
Characters from the initial three episodes can evade blaster fire and possess unique close attack moves (such as Chewbacca's ability to detach arms). New Jedi Force abilities, including the ability to invert Stormtrooper masks, have been added. The red power bricks from Lego Star Wars II, which unlock extras like invincibility and the minikit detector, are now present in the prequel levels.

When questioned about the absence of a PSP version, several sources revealed that Traveler's Tales had limited resources, preventing them from developing a PSP edition. However, LEGO Star Wars III: The Clone Wars was later released on the PSP.
