Well what makes Jedi Outcast so fun is the ability to fight using only light sabers. No guns.
It's like what Obi-wan once said about light sabers...
"A weapon for a more cilivized age."
I wouldn't have enjoyed Jedi Outcast as much as I did if there no light sabers and it was all guns, it would have been just another Quake III.
The force powers are not hard to use, just configure it properly. I have my Force activation key mapped to "F" and I usually join the dark side..hehe Lightning followed in with some slicing on Aggressive stance rules! (There are 3 saber stances by the way indicated by the half rouded light bar on the bottom right. Blue signifies Light stance, you hit quicker but do very little damage, Yellow for Medium average movement and damage, and Red for Aggressive you do major damage but you hit really slow.)
