Just to make sure this thread doesn't go without actual screenshots, here's a picture of my character (Kantaris) fighting sand people on Tatooine. She's a deciple of the dark side (Hence the red lightsabers).
Kantaris VS. Saber fodder
I normally play as good people in RPG's (I'm a very good-hearted person
I feel bad when I'm being mean), but the range of options and consequences available to a dark-side character is incredible. It's definately worth playing through at least once as both kinds of characters.
