Surprisingly Amazing.
It may be a love or hate game, but if you enjoyed Oblivion, you will enjoy this maybe even more.
The first 20 minutes is what throws people off to say its bad, but once you get used to how to play and learn the first few skills and things it becomes very addictive and fun.
The map is not the best to understand, but once you do its great.
It is not too easy, and not too hard, the difficulty is just perfect and you arent perfectly leveled with every enemy like in Oblivion.
There are plenty of different types of enemies and plenty of quests to fulfill.
There are loads of different types of items and managing them and customizing your character is fun, this game is awesome and the only thing I am a little disappointed in is the Current Gens graphics.
But the amazing gameplay and few second very rare load screens make up for it.
Online is great fun with friends, and will be even better once there is a patch.
