Almost unbearably slow to start, you are eventually introduced to a world filled with the type of adventure and drama that a good RPG needs. The High King is dead, murdered, the land gripped by civil war, and an ancient evil has returned to rain fire and ice from the sky. What more could you want?
It is hard to describe the feeling of freedom you get the first time you step off the path and realise the world is open to you. That the mountains in the distance aren't a backdrop, but real locations you can visit. Games like Oblivion and Fallout 3 were big, but they were also largely empty. Skyrim is a world full of life, adventure, and more content than you can shake an enchanted stick at.
Join the Mage's College and spend 6 to 8 hours investigating a mysterious magical artifact, fighting those who would claim it as their own. Join the Thieve's Guild and spend 6 to 8 hours helping them reclaim their former glory, and getting involved in an unexpected twist or two.
It would be easy to focus on the content, and ignore the rest of the game. Easy because compared to the content, the rest of the game is less impressive. That is not to say it is bad, just that it is not really anything to get excited about.
Combat has its moments, and is definately an improvement over Oblivion. But it feels unbalanced. Clearly a lot of time was spent on the intuitive and rather fun dual-weilding magic system, but mele, stealth, and ranged combat feels awkard and difficult to start.
But overall, the combat and skills system works. Reading a guide before starting would be highly recommended, but it is nice to have the freedom. Want to try and create a iron-clad battle mage? Go nuts! Want something more traditionally like a stealthy archer? You can do that too.

As a die-hard RPG fan, it would be easy to blindly give this game a perfect score. But the game lacks universal appeal, and with its dull start, average combat, and confusing interfaces, it doesn't deserve the score it's heritage should have bought it.
Must buy for RPG fans. Bargin-bin pickup for everyone else.
