I had to write a follow-up review now that about 3 years has passed since my last one, and two sequels to this game have been published.  Despite playing the newer games, I dusted off and fired up my old copy of Jedi Knight/Mystery of the Sith (JK/MOtS) and had a blast.  The two are obviously dated, but don't suffer as much in comparison in terms of game play as the original "Dark Forces" (circa 1994) had in light of JK/MOtS.  Like DF, all the games in the Jedi Knight series are first person shooters.  JK/MOtS added the lightsaber and force powers with an enhanced game engine - besides better graphics and sound, it was now possible to combine moth horizontal and vertical head movements using the mouse (DF had separate buttons for vertical looking, which made the interface feel exceedingly clunky in comparison).  Also, basic movements were more natural - you never had that feeling prevalent in DF that you were a golf cart instead of a person.
