Just to note I reinstalled Jedi Outcast (I want to play them in order) and I was right...Theres nothing more fun then cutting stormtroopers to pieces while throwing their friends down bottomless chasms.
The best is setting the Slow-Mo Deaths to "Excessive" and using the Stormy Decapitation Code. Boom, Headshot!
Jedi Academy was fun, but my favorite in the series was Jedi Knight: Dark Forces II, mainly because, for the time, it was the Best Game Ever. First 3D game to use a lightsaber, or something like that. Good story (though crap cutscenes), excellent music (straight from the RotJ Soundtrack), and epic level design (I loved how small and insignificant you felt). The others since haven't had the same feeling.
I might replay them once I finish Prey.
