Excellent story, great characters and awesome gameplay makes this game perfect by all means.
The gameplay it's in first person, You arsenal weapon consists in swords, hammers, axes, crossbows. It's so real the use of weapons that each time that you use it to kill your enemies they will begin to decrease their powers so you will have to restore it with some special tools that you can find.
The use of magics are great also. You have a lot of variety: conjuration, restoration, destruction, alteration... and all of this you can upgrade depending of your current use of them.
The enviroments are awesome. The world is huge and the cities looks perfect. It really feels like you are in the medieval age. The dungeons and caves are great too. They look creepy and the music is good as well.
Please do you a favor and by this game. You will not be disappointed.
