I've played Dark Forces, Dark Forces 2: JEdi Knight and JEdi Knight 2: Jedi Outcast (Which is actually DArk Forces 3). I've enjoyed all of them, especially DF2. I wish that I could play JK2 on my system but it uses 3DFX for the graphics, so I'm screwed on that front.
BTW, if anyone knows how to get around the 3DFX problem, PM me.
