Star Wars: Knights of the Old Republic 2
You follow the story of a Jedi who was exiled from the Jedi Order. The Order was almost wiped out by the Sith and you wake from unconsciousness with a mision to seek out the last few remaining Jedi.
Gameplay mechanics are virtually the same as Knights of the Old Republic although there are some notable additions such as the option to choose a fighting style while wielding a lightsabre. The mini-games of the first game are back, including swoop bike racing and Pazaak.
The full Knights of the Old Republic 2 walkthrough includes the original content plus the Restored Content mod which adds much more content that was left out in the original release.
