So, I've put in a fair amount of time in the game since it's release, and though I've enjoyed pretty much every aspect of the game, I've found myself growing bored with the challenge. I don't mean to make my life extremely difficult or anything, but I was ready to play the game a bit differently, so I started an Orc, and 50 hours later, this has been the most satisfying gaming experience ever. In short, I have completely shunned the leveling system, attempting instead to finish most of the content in the game with a level 1 character. Compared to how the game normally plays, this is night and day. To give you an example, I cleared shimmermist caves near whiterun, and the falmer were extremely difficult, but after 2 hrs of play, I managed it with careful strategy. It was a blast. Blocking IS important now, and so are poisons, potions, etc.
Yes, I do use smithing/enchanting/alchemy, but without perks, these only help boost basic gear a bit, but not too anything ridiculous. So far, the best armor I found was a set of Orcish armor, which I improved to flawless

, giving me 129 armor rating total. My best weapon is a flawless skyforged greatsword enchanted to do 10 pts of frost damage (33 base + 10 frost). The fun thing is that I explore dungeons in search of actual treasure, since it is sooo rare to get anything good in the chests, thus making each item you do find a very special piece of gear!
I really enjoy this playthrough, moreso that anything else I've done in an RPG, and I recommend people try it out! Oh, as a bonus, I've only saved 10 times so far (excluding autosaves), which also adds to the immersion! Anyhow, please share your thoughts and similar experiences. Thank you.
