You mean Star Wars: Dark Forces III: Jedi Knight II: Jedi Outcast? Yeah, that is a fun game. I actually also rather liked Star Wars: Dark Forces IV: Jedi Knight III: Jedi Outcast II: Jedi Academy.* ;)

Though it didn't go over as well as SWDF3JK2JO, I thought it had a lot of really fun new elements to it. Like the tauntauns, wampas, sandworms, and some other unique things I am probably forgetting. As much as I hate the prequels, one thing about them I always liked was the Jedi Master and Padawan thing, so I was actually pleased to see it show up in this game in the post-ROTJ EU setting. I also liked the branching mission system. Sadly, I never actually got to finish it, I reached a level that was too much for my computer and would always cause the game to crash. By the time I got a new computer I had kind of forgotten about it.

I think there is a version for the original Xbox, maybe it is backwards compatible with the 360. If so, I ought to try to find a copy.
