Oh my, I've spent far, far too many hours on Skyrim so far.
But its one hell of a game!
The combat has been a bit of a mixed bag. On one hand, if you play in 3rd Person View, you can actually judge distances and use techniques one picks up in the SCA. Because the AI doesn't automatically adjust for where you're standing as it delivers attacks, you can effectively sidestep or circle around your opponent. Its difficult but its doable.
You can also use distance to your advantage, stepping in to deliver blows and stepping away as they return them. But because there's no tactile sense involved this can sometimes fail.
Combine that with some sort of weird system whereby the computer fails to accurately sense the striking zone of a weapon, and its possible to miss someone directly in front of you and yet cut the person behind them. This is particularly troubling when that person is on your side, like a "Companion". Ordinarily Companions can't be killed by other NPCs because they "yield" and become a noncombatant when they drop to maybe 15% health.
Can't tell you the number of times I've killed my offsider whilst attacking some bandit that stands between us. :P
Most single handed weapons work fairly well, but two handed weapons strike stupidly slow. And on top of that, I'll often find myself clicking the mouse button 2-3 times to get my character to swing even once. One day I'd like to play a game where they actually went and field tested these weapons or maybe spoke to someone who actually knew how to fight with them. ;)
On the whole though, I'm having a bloody great time. :)
