I think it speaks more of my change in gaming preference over the years, however I was not able to get into Oblivion. I tried hard to like it, but could never actually get more than 2 hours in without just wanting to give up... so I did.
Since that time I've grown sick of online shooters and have completed a few RPGs (Mass effect/Fallout etc) and picked this up on the release date.
I've never really been one for too much wandering about - like in Fallout, I pretty much stuck to the main quests and didn't find exploring all that rewarding (mostly because you just rnu out of ammo or get killed too often).
Skyrim however, like a lot of people here, I have spent 25 hours on so far and I've done one of the story quest objectives. I've done and found some really entertaining side quests, none of which have felt laborious thus far. The game does a fantastic job of making you feel like you can go anywhere and do anything... and BE any type of character.
I was worried also that a load of the traditional RPG elements, such as choosing attributes, would be too complicated, but it really isn't!
As much as I'd like to say that you should not buy a hyped game if your gut-feel is that you wont like it ( I did just this with BF3), but I think you might be pleasantly surprsed by this.
