I loved walking into a shop that I would have no reason to need to go in and wreck it completely, just watching the helpless shopkeeper look on as his shop was destroyed was pure gold.
Also, I reckon I'll fast-travel less in Skyrim, I'll have a hell of a lot of free time to play it, so I think I'll ride horses and walk more, just so I can enjoy the scenery and all the random events that seem to occur. I imagine that would make the experience a whole lot better. Especially because it looks so easy to get sidetracked by other areas of interest, such as accidently stumbling upon a hidden cave or house with some sort of secret inside, that's what I love about the Elder Scrolls games, just how unknown everything is, it's not predictable.
Jesus Christ I can't wait for this game...
