A guess a little personal input wouldn't be remiss to make it feel like you're actually an active participant. But is it really so bad to be a silent observer, anyway? I think it's a bit better than being pandered to and treated like The Chosen one all the time. Obviously some kind of middle-ground between the two extremes might be ideal also but sometimes being the center of attention actually seems out of place in the context of the stories given and comes off a little cheesy.

The SW:TOR pick-your-path dialogue trees would be nice to have, but maybe a waste of time when you think about it.
