This is Elder Scrolls, remember? Our character will never have voiced dialogue, and the text dialogue is never personalized; they're just topics of interest. Where did you get the idea that we can be nice or mean through dialogue?
I do remember, and I'm glad they will never have a voice. I also remember many lines of dialoge that could make you sould like a complete jerk if you wanted too. It really was only in the tutorial thing mostly, a few other places here and there. It was more so in fallout, and I'd be surprised if there wasn't more dialoge options like fallout, where you could choose how you talk along as how you play.
And, that still doesn't take away from the fact that you do talk a lot to people, be it just asking about topics of interest or whatever.
