I noticed that I'm leveling obscenely fast. I read a skill book for lockpicking and went from nothing to 50% full for the next level. On the next skill gain, I made a level (that means TWO skill gains).
Then I turned around and did it again -- I haven't even left the first 'dungeon' early in the game (where you go to retrieve a [item] for [a guy] from some [bad guys] in a [crypt]). I haven't even figured out how I want to even play the character, yet I'm burning through levels. :/ It makes me feel like I made some horrible mistake by not knowing exactly what I was going to do before I even started the tutorial.
