I have some now already read about this game - both positive as well as negative feedback. I can only say play After 15 hours: My expectations were exceeded. Since I'm a big fan of Lord of the Rings and The Hobbit, I had to have just the game. I must say also that I have never had such a game (with sword, bow and arrow, etc.). For me it's the perfect game. An open game world - though for not as big as in Assasins Creed or GTA, but big enough to enjoy the game a long time. Some of the battles have vastly in yourself and you do not want to give up before you have defeated his opponent - which is not always easy when the whole Uruk come to the rescue.
Otherwise it was already written enough :-) My conclusion: Absolutely buy and play! It is worth it !!!
