To be honest though I see the dialouge thing a good thing at times, you tend to get fed up in oblivion and morrowind with the fact of every NPC saying all the same thing (in oblivion it kept the same voices etc etc) so the limitation in its own right is a bad thing but to me is a better thing so we don't get the same stuff we already know.
I think if this is implemented properly it will create a more immersive atmosphere. Imagine how NPCs are implemented in Red Dead Redemption. I think that game is very immersive, but I can't talk to every NPC about everything can I?
I think that what we will actually see is better voice acting, more unique NPCs and just better environments altogether. I have been pretty optimistic about this game on almost all counts, but it doesn't come without reasoning. The reasons behind many of the changes I think are for the better. Time will tell won't it!
Why the hell do the people always defend Bethesda?
Some feel personally attacked when it seems others haven't thought everything through and are complaining or criticizing an element. Also, people generally want to resolve issues that are brought up. It is only natural. Since this forum provides a community setting we all feel like we are part of the same body, or 'club'.
There are some who do not really have a good defense against somebody's criticism and that can become annoying if all you hear are attacks from people asking you to stop criticizing or to keep quiet. However, as I have said in this post, myself and others are trying to objectively look at the changes and see why Bethesda would make the actions they make. All of us are essentially equipped with the same source of information here in the community, but some of us have better reasoning powers.
Opinions are welcome however, otherwise nothing is resolved. If you don't express how you feel to others you might not have the chance to change your perception and receive counsel from other members.
