Knights of the Old Republic is a Star Wars computer game being made for Lucasarts by the people who wrote the very high-qaulity (and massivle popular) Baldur's Gate games, and the soon to be releasedd (and astonishing looking) Neverwinter Nights (they also did Planescape: Torment and Icewind Dale, all similar RPG type games and each worht buying).
It is set during the last Sith War (either 1000 or 2000 years before TPM; seems a little unclear) and players play either Jedi or Sith in that conflict. Knowing these guys it will probably have a very strong story-based element and good multi-player modes.
Mind you, it has been a while since I checked up on this game; then again info on it is hard to find.
Should be out around the same time as Jedi Outcast... that'll be a good month.
