Not gonna read a "first exclusive" review, these are always worthless.
I watched some of the streams and IMHO this game is a 10/10.
Indeed, you´re so excited you could burst!
Anyway, I don´t think one can adequately rate this type of game just by watching few streams and having access to preview infos.
For one, an important question is how sustainable the game´s entertainment value is.
First few dungeons will no doubt be exciting, but are the dungeons distinct/elaborate/varied enough so that it takes respectable time till the feeling of déjà vu/repetition creeps in?
How varied the side quests are design-wise?
What about challenge and balancing at higher levels?
And so on.
Though, for what it´s worth, few streams I´ve watched had mostly positive effects on me as well.
Just comparing the streams to Oblivion, my impression is there´s a lot of stuff better handled in Skyrim, like world design, art direction, level scaling, crafting, liveliness, factions (lack of emphasis on political aspects was a big mistake in Oblivion imo), choices, faces, writing, lore, voice acting, music (apparently including some tracks directly from
general attention to detail, character development (I really like how the shouts feature is tied to exploration) and there are only few things that didn´t jump at me as immediate improvements, like AI, UI, melee combat or some of the Gamebryo© stuff (terrain stuckage or giants bashing players to stratosphere).
In the 3 hours long stream, there was a moment when the guy was running around tundra at night, high mountains in the distance, aurora borealis in the sky and fireflies flying around, which together resulted in a great "piece of atmosphere".
From where I´m sitting, by now there are good chances that Skyrim will be quite substantially better than its predecessor.
