You don't necessarily have to be the goody goody Jedi (although you can), you will have options to play the more forceful and vengeful Jedi as well. From this video we also can see how diverse the Jedi class is, from playing the sneaky rogue style of game play, or straight on damage dealer, Jedi have a little of something for everyone.
The Lightsaber battles are probably the largest parts of the Star Wars series, and by the look of this video, BioWare seems to be putting that extra polish on, and making sure players get the full Lightsaber dueling experience. Honestly the duels could look really cool or turn into a bunch of rag dolls flailing glowing sticks at each other. Hopefully Bioware can pull off some epic battles and really draw the Star Wars fan into these fights.
