One thing I found annoying is when I followed (spoiler for those who haven't played the first couple of hours)
through the village, he stopped greeted me repeatedly. Every five seconds pretty much. Kind of awkward. Other than that, there's not much except for forced third person riding and the ability to be left-handed (shield in right hand).
And the character creator was kind of disappointing. You can't adjust the angle of your eyes or nose, adjust nose width or eye size etc. And there's no ponytail haircut for Nords! Doesn't matter much but it's a very basic hairstyle. Also, I was looking forward to huge braided beards and stuff. There's only a knotted one, with one knot

I think the game is amazing though, definitely the best TES yet. The combat is a lot of fun, and I'm using magic (dual wielded fire spell and healing), archery and melee combat (axe + shield), and it is very easy to swap between styles quickly, and to learn how to. I recommend everybody to play on Expert! The game will be much more satisfying and intense!
