Star Wars: Knights of the Old Republic

Star Wars: Knights of the Old Republic (sometimes known simply as Knights of the Old Republic or KOTOR) is a role-playing video game set in the Star Wars universe. Developed by BioWare and published by LucasArts, the game was released for the Xbox on July 15, 2003, and for Microsoft Windows on November 19, 2003. The game was later ported to Mac OS X, iOS, and Android by Aspyr, and it is playable on the Xbox 360 and Xbox One via their respective backward compatibility features.

The story of Knights of the Old Republic takes place almost 4,000 years before the formation of the Galactic Empire, where Darth Malak, a Dark Lord of the Sith, has unleashed a Sith armada against the Republic. The player character, as a Jedi, must venture to different planets in the galaxy to defeat Malak. Players choose from three character classes and customize their characters at the beginning of the game, and engage in round-based combat against enemies. Through interacting with other characters and making plot decisions, the alignment system will determine whether the player's character aligns with the light or dark side of the Force.
