Gamer.no gives a 9/10 score
From the Conclusion of the Norweigan review (my translation to english):
"It is an enjoyable experience to play Risen from beginning to end. A difficult, trying and challenging pleasure, but the hardships only makes the game better. There is simply not much negative to say about Risen. It is perhaps not as ambitious as Gothic 3, Oblivion, or Fallout 3, but it serves as a much more focused and streamlined gameplay experience.
The only reason Risen does not get absolute top marks from me is that it does not challenge its genre or are innovative in any way. It is instead just a lot better than the predecessors in the same style. This is an RPG that should be tested by all lovers of the genre who do not mind a little hectic button bashing".
About the graphics (Google Translate):
"The game's graphics are also good. It is perhaps not as polished as those of many other new games, but it has its very own realistic charm. The matter is clearly better than the graphics in the other Gothic games, even if the style is largely the same. Risen also seems to largely have avoided one of Gothic 3's major weaknesses, namely the technical.
Risen requires a good PC to run the best possible graphics, but with fairly new hardware should be most able to run the game stable, beautiful and good. I'm sure the developer can improve a few small bugs and performance features in the weeks after the game's launch, but I had at least a good technical game experience with the Risen".
