I've been playing through KOTOR again after many years. One thing that I've noticed is that the Dark Side has all the nuance of a Khorne Berzerker. You're pretty much give Choice A: Do a goodly act for somebody else Choice B: Do nothing and walk away Choice C: Stab everybody in close proximity then see if you can find any kittens to drown . Similarly, the Dark Forces series usually takes the route of strangling innocent bystanders and shooting droids rather than seeking personal gain or playing two opponents against each other. And The Force Unleashed seems to have just treated the Dark Side as Force steroids with the anger just a byproduct of all the UNLIMITED POWAH and you were just a normal guy otherwise.
Was there ever a Star Wars game that not only understood the insidious nature of the Dark Side, but also that it influenced people in many different ways besides 'raging meth addict'?
