This game blows my mind. It's great. I loved Morrowind, was kinda bummed by Oblivion, and Skyrim makes it all better. Here are some examples of greatness:
I really enjoy the finishing move flourishes you do, such as chopping out enemy legs and smacking them down with your axe, roundhouse slashes with 2 one handed swords or wicked stabs all the way through and throwing them off your weapon. I thought it was cool until I got too close to the dragon I was fighting with my mage and got below a quarter health... It grabbed me in it's mouth, shook it's head back and forth, and then THREW ME off the mountain. I was laughing the whole time. Then I reloaded and killed that sucker with FIRE!!!
Don't mess with Giants in packs. They have an annoying habit of bouncing you off the dirt. I got one pissed at me and chasing me across the plains when a mudcrab started a fight with the giant. Giant turns around and punts the mudcrab. Mudcrab goes into orbit. Seriously! I would say it's a glitch, one time only, but I reloaded and THE SAME THING HAPPENED!!! Mudcrabs in space. They are out there!
Experience varies by race and play style. Playing as an orc character I was invited into an orc stronghold just before a dragon attacked that stronghold. Later as my Dark Elf mage I went to the same stronghold and needed to do a quest to get in, and no dragon (because most dragon city attacks are random). Conversations are different depending on race and play style. I disenchanted my robes once and walked around until somebody said 'oh my gosh, you are naked!'. Every day is a new experience.
Horses have 4 wheel drive. Grab a horse and climb a mountain. It might be a glitch, but you can seriously walk up almost any slope without a problem. The maximum slope that a horse can climb is several degrees greater than what you can climb up. It's probably a glitch that will be fixed soon, but exploit it while you can. Lots of words are hanging out at the top of skyrims mountains, but beware for most are guarded by dragons and worse.
