Played 3 hours so far PC version. I kept crashing to the desktop during the carriage ride but after changing sound settings the problem was solved.
My first impressions were good, i loved the starting scene(won't mention it due to spoilers)
Anyway, regarding one of the big complaints for PC users the UI, during the first hour of play i agreed and disliked the UI, it took forever just to change weapons or grab a potion etc... not being able to see my Orc in the inventory.
That changed after 3 hours of playing i finally started using the favorites tab sticking my best weapons,potions and spells in there and getting used to changing over quickly when different enemies popped up.
I don't have much to say as of yet as i have only played 3 hours but can say that so far i am enjoying Skyrim A LOT.
