After about three hours of play, the feel of Skyrim is much different from that of Oblivion. First off the "Novice" difficulty is less forgiving than that in Oblivion; in this setting you're not a god smiting everything that moves in one blow. You actually feel like your life is in danger when you go charging hammer-first into battle, and it's very nice.
Also, when your character swings his weaponLolol it actually feels like there's some force behind it, and it will hurt when it hits the enemy. Perhaps this was because they made normal blows feel like Oblivion's power strikes, and made the controller vibrate whenever you cast a blow.
