kotor is only going to be a trilogy i mean how long can the dark side (sith) live for they just keep getting destroyed then coming back again then get destroyed then come back again then get destroyed then come back again and so on ..........
for dark side robes there should be a hood over your head so you look more dark sideish, such as when i got revans robes i thought there would be a hood over your head like in the cinamatics which will look kool while wearing a sith mask
