EDIT - come to think about it, NWN2: Mask of the Betrayer wasn't a "save the world" quest either. It was a story about curing the curse of the soul eater. It was actually pretty much an AWESOME story if you can tolerate the NWN2 engine anymore.
I played all the NWN games and Mask of the Betrayer is definitely one of my favorite ones. Come to think of it, I never felt like the main savior in most NWN games. It was more about taking care of certain problems etc. Although, the world was restricted by loading screens, all the earlier NWN games felt very immersive.
I've said it before, Bethseda has a lot to learn from Bioware, when it comes to relationship issues and/or NPC reactions/interactions with your character (NWN: Hordes of the Underdark - all time fav. Love Valen <3 hehe).
Don't get me wrong, I'm a HUGE HUGE TES fan and I love the open world of Tamriel. But I guess, after Oblivion, which was one of my all time fav games, I had high expectations for the next installment in the TES series. Did I set my expectations too high? After waiting for over five years for the next game, did I anticipate things that are still beyond what Beth can do?
How hard is it to write a few rules in the NPC program, in order to create some consequences for our actions?
EDIT: Someone just said that they want to care about the story line. I guess that's what I loved about Oblivion. Martin Septim - I cared about him! I cared that he was insecure, that he wanted to do what is necessary to help Cyrodiil/Tamriel. I would've walked into the hells of Oblivion for him... which I did LOL
