Yes.
When it was announced, I swore I wouldn't bother. Then the comparison videos started appearing, and my brother owes me a birthday present, and Skyrim is pretty much my favourite game of all time (even better than my previous favourite, Street Fighter 2), so I have to have it.
Another couple of hundred hours will be spent on it I'm sure.
I'm already thinking what character I'll go with for the first play through. I think I'll do a pure mage (robes only, no armour) as I really enjoyed that last time I did it, and I think conjuration. The Ritual stone power when there are loads of corpses about it always a laugh. Not sure it that will be powerful enough for master difficulty, but we shall see.
