I was never able to get the hang of lightsaber combat in Jedi Outcast. Too frenetic. Still fun though.
I've always wanted to see the Arkham style of combat tried with lightsabers.
Oh man, that'd be GREAT! Albeit, you'd still need a good story and underlying game. But yes, an Arkham style open world combat game but set in the Star Wars universe? Please and thank you!
As for the Jedi Outcast combat, the first thing you have to realize is that the combat models themselves were seriously different between SP and MP. SP combat was far more cinematic, had more things like automatic blocks (as I recall, anyway), and your "special" moves tended to be more showstopping. MP combat was basically designed to be kids swinging glowing whiffle bats around at each other, and it went through some HORRIBLE patches before it eventually leveled out.
I played a fair bit of the MP combat and was pretty involved in one of the online communities surrounding the game, and I remember some of this stuff vividly. There always seemed to be a single "best" move that was both unblockable and basically a one-hit kill. For a while it was the "red" style's death-from-above jump attack. Then, oddly, it became the backstab move that you could do in, I think, "yellow" style. That led to a period of the game where it was dominated by "ass-masters," aka people running around backwards the whole game just on the off chance they could execute the backstab move. You also had people who wrote macros for the game so they could hit a button and execute a series of moves with zero delay (e.g., turn 180, hit "back," and execute the special attack all with a single button press).
Frankly, I never liked the MP sabre combat because it just...made no sense. You were supposed to have a largely weightless omnidirectional blade which could only be blocked effectively by a LOT of mass, another sabre, or specially treated armor which was only marginally effective. And yet, the game made it seem like if you swung slower and "harder" (which -- think about it -- DOESN'T MAKE SENSE), you'd hit harder and cause more damage, whereas light taps would cause less damage. The whole underlying design would've been more at home in some medieval combat game where each weapon was different (e.g. "red" style was a giant maul, "yellow" style was a longsword, and "blue" style was a rapier). But they mushed it all together in the lightsabre.
I don't remember the combat itself all that clearly, but to my recollection, TFU didn't do a lot better. Nobody has ever released a game commercially that gets lightsabre combat "right" in my opinion. I doubt they'll start now. I'm not even sure it's possible at this point.
