There aren't dialogue tress in BD. You talk to people, you pick the glaringly obvious options, and if you mess up...well you just talk again and pick the other options again and again. Dialogue trees are like those in Torment, where you have several options and the outcome of the immediate task alters depending on what you say and you can only say it once.
PS:T (and for that matter, BG2) were highly unusual in that regard. The same applies to A-Sharp's King of Dragon Pass--which you ought to like a lot, since it really offers an enormous variety of choices at every turn. (It's among my favorites.) But even extremely non-Diablo like games eliminate dialog trees: Ultima VII, for example, KotoR and Betrayal at Krondor. Dialog trees have to lead to multiple outcomes, or they're phony and looks it. Judging <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> by the absence of dialog trees is a bit of a non-starter, in that sense. Each to their own, but I prefer to judge a CRPG by its interactivity with the environment. <img src="/ubbthreads/images/graemlins/beyond.gif" alt="" /> scores pretty well there. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
