What an odd review.
First, the reviewer seems to lack general info prior to trying the game out. Second, he adresses the bugs like framerate and graphics that are below industry-standard, which is understandable. Third, he likes the rest: excellent music, voiceacting, story, characters and so on, hinting that gameplay is king. But then the low score, atleast from reading the Gamespot review, you knew that the score wouldn't be that high.
