I like the lower levels best, say from 1 to 20. After that it gets too easy. I'd like it best if I could pick the advances I would have had at level 20, assign them as I please to my character to create the type of character I want then no matter how much I use a skill after that it stays the same. I want the NPC's and creatures to be picked randomly from the entire range of challenges so you would never know if you would be fighting something easy or hard. I just don't really care for the whole concept of "leveling" up until you are at the max for everything which is pretty much unavoidable.

I tend to like my character best from about level 15-30, feels just about right in that region.

15-30 On Adept

I have little interest in "growing more uber as I level." So when playing most characters I tend to like levels 1-10 the best.

Pretty much all them, except when I'm level 1.

What about Skyrim 4? Did you like level 1 in that game?
