I agree that Kotor was definitely too easy to complete. Hopefully the sequel will be made a little more challenging. Different difficulty settings would certainly add to the gaming experience, as well as the replay value.
I think the few times that he actually had something to say were enough to last throughout the whole game,considering that it took 5 hours of groaning and growling (most irritating) to say 3 words in Wookie language.
For my first game I will do DS-DS.Why? Because I like being bad.
(I will of course explore all my options in the game,so I will eventually play the lightside too.)
