I've had Skyrim since Christmas, and I've already managed to break in to the twenties! My character mainly focuses on Sneaking, Archery (the two of these together make me feel like a god at times) and one-handed skills, though I prefer to dual-wield instead of using a shield because it provides a lot quicker means of chopping down a few foes here and there... plus, I'm not much of a blocker when it comes to fighting
I'm astounded by how in-depth and immersive this game actually is. Nearly every quest feels as though it was given as much care as the main story line (the majority of them ever surpass the main story lines in quality, in my opinion.) Though, I'm much more of a "go-as-I-please, do-what-I-want" kind of person when it comes to playing, just because it gives me a little more sense of the role-playing field of the game, which is done fantastically. Definitely has earned a spot as one of my favorite video games.
