Star Wars: Knights of the Old Republic II: The Sith Lords

Five years after the events depicted in Knights of the Old Republic, the Sith have become stronger and more determined to rule the Galaxy. The Jedi Order is nearly exterminated. A mysterious ex-Jedi has been exiled from the Order and is traveling alone. This Jedi had served under Darth Revan (when the latter was still on the Light side of the Force) during the Mandalorian Wars, but due to enigmatic circumstances was forced to retire. Now the past is catching up with the Jedi, and soon he or she will have to choose the side to fight on.

The Sith Lords looks and plays very similarly to its predecessor, also being based on the Star Wars d20 role-playing rule set (which, in its turn, is similar to the 3rd Edition of Dungeons & Dragons) and having the same combat engine, character development, and a Light and Dark ethical system, which judges the player's decisions and actions and influences story events and characters' responses. Additions to the gameplay include a lightsaber-crafting system, which allows augmenting lightsabers with various items, new Force powers, and the possibility to influence the alignments of the characters in the player-controlled party through conversation choices and other decisions.
