I think one of the reasons why I'm skeptical is because it sounds a little like Fable to me. I hope they didn't hear this idea during the development of Fable and decide they'd implement it without deciding if it was really worth fleshing out. Needless to say, the less Skyrim is like Fable, the more I'm going to enjoy it. So many ideas get thrown into video games even though there really isn't a passionate feeling of game improvement. Some times just too much money is sunk it a project that they figure it's just too expensive to abandon or omit.
Sorry Fable fans...if there are any out there.
But I will agree that the more nuanced it is the more I'll enjoy it. A simple system that is extremely easy to manipulate won't be fun. A system that is too adaptive to manipulate won't be fun either. They have to find that sweet spot that in some way lets us improve our experience. We'll see what happens.
There is a difference between Bethesda and Lionhead. Bethesda doesn't have a guy that says he has so many features that he doesn't really have. Sure, Todd has made some mistakes, ala Oblivion, but he doesn't say his game is going to be a "Fable killer" or something like that then get a 7/10.
But town economies sound awesome, I really can't wait to see what I can corrupt, especially as a thief.
