Mostly Stormcloak, but in retrospect I don't like either of them, and possibly I even like Imperial more. As far as characters, I made 4, an Orc (two-handed), a High Elf (pure magic), a Khajiit (SnS) and an Argonian (assassin), so I think I pretty much like anything non-human. That said, I liked the Orc best, so that's what I'm going to examine. Virtually never used health potions (same with any game for me, I'd rather grind than stoop to using them), two-handed all the way (so unfortunately no magic aside from some practical self-healing), virtually never blocked just because I didn't realise how it worked until later, used Beserk if there was something I couldn't take out by hacking and slashing, smithing and enchanting to the MAX (those are really the only things you need, screw every other skill), was a werewolf but never used it because I like my loot, would walk like a snail for hours if I had to to get loot back to a chest, mostly acted justly, but since it was my first character, I also compromised that a lot for the sake of playing the game. I destroyed the Brotherhood, but I wouldn't have joined the Theives or College.
