Initially I gave this game a negative review, but after giving Dark Forces a try and replaying Force Unleashed and then this, I'm feeling a lot more charitable towards it.
While my old criticisms still stand (the lightsaber duels being basically luck-based, a few overpowered enemies (particularly the snipers and the grenade-spamming space goats), and the stealth mission being the absolute worst idea the devs ever had), and while I still think that Jedi Academy has more polished gameplay, Jedi Outcast is still a very well put together installment, and considerably more substantial (Jedi Academy mostly being a series of brief "episodes" with full levels marking the main acts).
Interestingly, I find the game is at its best in the first two levels before you get any Force powers, where you're basically playing a graphically enhanced, more linear expansion to the original Dark Forces, making me feel oddly nostalgic about callbacks to a game I only played a few weeks ago. The level design is tighter there, giving the locales a sense of continuity and scale that later parts of the game are simply lacking. I think this can be attributed to the fact that with things like Force Jump in your arsenal, the developers felt they needed to give you wide-open spaces with which to take advantage of it, which turns the levels into the "squiggly linear corridor" school of lazy level design.
Even so, the levels are still fairly varied in their design, even if they feel more... "gamey" for a lack of a better word. Setpieces, not locations. Especially with the rampant Bottomless Pit abuse. Include more than one completely nonsensical example where you know said pit couldn't possibly fit in the dimensions of the location you're in, like onboard the Doomgiver, a ship that's maybe 5 stories tall at most given the orbital drop pods visible on its underside.
But that's nitpicking. The Dark Forces Saga is still probably the most EU-friendly entry into the Star Wars gaming library, and Kyle Katarn is still likable badass. Jedi Outcast is not without its major flaws, but if you can stomach them I can't in good conscience call it a bad game.
