What gets me is I have over 30 hours logged into this game now and I still have only been to half of towns you can go to, I still Haven't seen most of the world!!
Yeah, I'm over 30 hours too and 90% of my gameplay time has been around Whiterun Hold. And I feel as if I've only done about 20% of the quests obtainable there.
I'm unsure about how much I'll hang around the northern regions though, as incredibly cold climates aren't my favourite.
Currently I'm headed towards Markath simply because I started playing without a compass on and got drawn to the incredibly beautiful canyon which leads you there.
