I thought I didn't have the darkness in me, but the developers at obsidian made it easy for me this time.
I couldn't believe it when, as a lightsider, I met the Jedi Masters on Dantooine and they decided they were going to cut me off from the force. Frickin' AHs. I was like, "Man I shoulda killed you guys when you were alone you ungrateful, pompous, arrogant mothers."
I just killed Master Vrook and it felt GOOOOD.
It's also WAY easier to exploit the infinite XP inside the secret tomb as a Darksider.
Not to mention, as a darkside female, when you unequip all armor and clothing she wears a "Kill Bill" style black and red body suit. It can be quite distracting. I think that when she runs around like that she should get a plus Five to charisma
