Same here; I've put in about 40 hours (level 30), and I'm still loving it. Primary weapon is daggers, and secondary is bow. Daggers are very fast, so I can usually interrupt enemy attacks and keep them "stun-locked".
The skill I use most is Detect Hidden, and Persuasion. For the other skills, I'm getting by with only a few points. I can unlock very hard locks with only a few points in Lockpicking (and buying lockpicks), and get by with finding potions and crafting Minor/Greater Healing (I don't use other types of potions...). I don't care if I blow up a chest with my low Dispelling skill; I heal myself, and if I get cursed, I find a healer. I haven't crafted any weapons or armor; I just use what I find.
