Im trying not to go straight to the other cities right away....feels so much better when you see a city in the distance getting bigger and bigger, i will be using the carts at some point though.
Yes, I prefer running myself, but it's nice to discover a new location when u need to visit the city later on.
Winterhold, mage college for instance with my dark elf character (I trained perks in multicasting in the destruction school and it was fun.)

And with all the perks in-game, it's so many ways to play a character so I'm really excited.

I'm also into necromancy, I raised a zombie after I killed a bandit.
The bandit zombie growled; kill, kill, and ran after another robber, it was hilarious and amazing graphic! haha.
